I have a problem with spaces between the words in Latex math mode. I have to write text in math mode because of the work I'm doing, and I already did the job. But the words are sooo tightly closed to each other. An example is as below :
It's the code in latex:
$>>> if ret is True:$\\
The output is something like:
ifretisTrue
You see? Sooo close to each other. I need a kind of command to set the spaces between words for all the math equations throughout the entire document.
In math mode LaTeX adds spacing based on mathematical rules. If you want to typeset text in math mode, use \text{}. In your case $\text{>>> if ret is True:}$\\ outputs what you want if you really want to put that in math mode.
By the way, it's better to ask LaTeX related questions at https://tex.stackexchange.com/

My question in short is: How can you create a boxed text with a label that can be referenced?
Background: I am generating LaTeX output from a Markdown document to be included in a larger LaTeX document. I would like to describe the steps of an algorithm as boxed text with a label that can be referenced. I know how to create a labeled figure and how to create boxed text, but I haven't been able to figure out how to combine the two, i.e. how to label the boxed text as if it was a figure, or how to include the text in a figure (other than converting it to an image, which I'd like to avoid).
An initial "solution": Just putting a the box and an empty figure next to each other (see below) kind of works, except that nothing ensures that the figure label won't float away from the box as I work on the document, since figures are floating objects while text boxes are part of the text, and the two are handled differently by LaTeX. Moreover, you may need to use LaTeX vertical space commands to make it look reasonably good, but it is hard to get it perfect. Is there a simple solution? Thanks!
P.S. I know that I could just switch to LaTeX and figure out a solution there, but here I am looking for a solution in Markdown, possibly making use of some embedded LaTeX commands.
You can see the algorithm in Figure \ref{methods:estimating}.
\fbox{\parbox{5in}{
1. Initialize $b_r=0$ for $r=1..R$ \\
2. For each item $i, i=1..U$, calculate ... \\
3. Re-estimate ... \\
4. Proceed to Step 2 until it converges.

It is rendered like this:
You can use one of the packages for writing algorithms. See https://www.sharelatex.com/learn/algorithms.
Mathematica appears to have difficulty horizontally aligning accents (e.g. bars, hats, and tildes) when placed on top of certain mathematical symbols.
Here's a simple example:
Using the AdjustmentBox typesetting construct (or Alt-Left/Right arrow in the frontend), one can manually adjust the relative horizontal position of the hat and the symbol j to produce the more aesthetically pleasing:
There are two problems here:
1). It is inconvenient and time-consuming to make these manual adjustments when this should really be the job of the typesetting engine proper. Indeed, LaTeX is able to position accents correctly over all of the standard symbols (roman and greek letter forms) without the need to manually tweak their relative positioning.
2). The relative re-positioning of the symbols using AdjustmentBox is lost when exporting the Notebook to PDF for printing and re-distribution.
Question:
Does anyone have any suggestions for a more convenient way (preferably automatic) to improve the typeset quality of formulas in Mathematica notebooks that use accents, that preferably will also survive export of the notebook document to PDF format before printing?
You can select " ĵ " from the Windows character map and paste it in.
Style[ĵ, Italic, 24, Bold, FontFamily -> "Times"]
Also you can assign it to an input alias (borrowing from Andrew Moylan)
n = SelectedNotebook[];
SetOptions[n,
InputAliases ->
Append[Options[n, InputAliases][[1, 2]], "j^" -> "ĵ"]]
Typing Escj^Esc produces ĵ.
Well, I do not think that this is possible.
You may ask Wolfram Research to include unicode character 0135 , i.e., they should add \[JHat], like
\[IHat]. Then italics display nicely.
I'm trying to get my code snippets to look as good as possible and so far I'm having troubles with the character spacing. Here is an example of the output:
alt text http://grab.by/grabs/2bb230de7c088d007733f52b95a40363.png
While the text in small is perfect, all the keywords that are in capital letters look terrible. Here are the settings I use
\lstset{basicstyle=\footnotesize, basewidth=0.5em}
If I increase the basewidth, the capital letters look good, but I can't get any decent sized line of code in one line. The following example does not fit in a page and I already put two line breaks in:
alt text http://grab.by/grabs/97ec29aa5a6811ce28bcd30bd389b52f.png
Does anyone have a clue how I can get this to work? Using \ttfamily does the trick, however, I'd prefer keeping the font.
Thanks.
If you prioritize looking nice, then using flexible colums is preferable:
\lstset{basicstyle=\footnotesize, columns=fullflexible}
You "obviously" need to scale the capital letters down horizontally. I do not know of a way to do this without actually editing the font itself.
However, you could put the entire listing into a \scalebox resp. \resizebox (from the graphicx package).
On a side note, the font you are using seems a bit strange, though, since the distance between small letters is significantly bigger than that between capital letters.
I have a block of text in a quotation. Some of that text will be in a very small font (\scriptsize) and some much bigger (\Large). My problem is that the letters in the big font push right up against the letters in the line above. This effect is unacceptably distracting to the reader. (Trust me; for my use, it is.)
My question, then: how do I insert space to push apart the lines so that the large text does not scrape against the text above it?
You can specify \vspace in postscript points. This will give you very fine-grained control.
or...
you can use the setspace package: \usepackage{setspace} then use the commands:
\singlespacing
\onehalfspacing
\doublespacing
or...
you can use \linespacing{factor}: Use
\linespread{1.3} for "one and a half" line spacing, and
\linespread{1.6} for "double" line spacing.
Normally the lines are not spread, so the default line spread factor is 1.
There are myriad methods, but in paper writing, I often use a \vspace{0.75cm} after the separating newline (I'm metric, so pick a unit you like).
There are four kinds of 'dashes' in LaTeX: hyphen, en-dash(--), em-dash(---) and minus $-$. They are used for, respectively, hyphenation and joining words, indicating a range, punctuation, and a mathematical symbol. My question is: how do I indicate an en-dash (range) in math mode? (as in $S=1 to 2$)? Do I have to drop out of math mode in the middle of the 'equation' ($S=1$--$2$)? Or is there a symbol I can use and stay in math mode? I tried $S=1\--2$ but this gives me a minus, not a en-dash, and $S=1--2$ gives two minuses. My guess is I am going to have to drop out of math mode but maybe there is a way to do it without that.
The simplest way is to use $S=1\mbox{--}2$. If you already have \usepackage{amsmath} in your document's preamble, however, you're better off using \text: $S=1\text{--}2$ because \text will adjust the size of the font when used in super- and subscripts: $S_{1\text{--}2}=0$.
An en dash used in math may easily be confused with a minus sign. You may want to look at other techniques for indicating a range such as ellipses (\ldots for dots on the baseline [used between commas], or \cdots for centered dots [used between centered operators such as plus signs]) or using the bracket notation. Some examples:
$S = \{1, 2, \ldots, n\}$ indicates an element in the set containing integers between 1 and $n$.
$S = [0, 1]$ indicates a real number between 0 and 1 (inclusive).
You can use \textrm which does not depend on \usepackage{amsmath}.
Some examples:
$S=1\textrm{--}2$
$S_{1\textrm{--}2}=0$ % correctly changes the font size for subscript
$S_{1\textrm{2}2}=0$ % does not change the font size :(
Or maybe use \textnormal instead of \textrm.
See also LaTeX: use \textnormal instead of \textrm (or \textsf) in math.
Well, you could use $1\mbox{--}2$, but I'd look at the list of math symbols in the symbol list. Hmm. I don't find one.
Use the command \leftrightline in the package MnSymbol. I don't know if it's the length needed for your purposes, but hopefully it will do the trick.
