How to make the output of Maxima cleaner?
maxima
Solution
(1) To suppress output, terminate input expressions with dollar sign (i.e. `$`) instead of semicolon (i.e. `;`).
(2) To get just the TeX-ified expression sans the environment delimiters (i.e. `$$`), call `tex1` instead of `tex`. Note that `tex1` returns a string, which you have to print yourself (while `tex` prints it for you).
Combining these ideas with the stuff you showed, I think your program could look like this:
"x: 1/2$ print(tex1(\f(x)))$"
I think you might find the Maxima mailing list helpful. I'm pretty sure there have been several attempts to create a system such as the one you describe. You can also look at the documentation.
Problem
I want to make use of Maxima as the backend to solve some computations used in my LaTeX input file. I did the following steps. Step 1 Download and install Maxima. Step 2 Create a batch file named `cas.bat` (for example) as follows. ``` rem cas.bat echo off set PATH=%PATH%;"C:\Program Files (x86)\Maxima-5.31.2\bin" maxima --very-quiet -r %1 > solution.tex ``` Save the batch in the same directory in which your input file below exists. It is just for the sake of simplicity. Step 3 Create the input file named `main.tex` (for example) as follows. ``` % main.tex \documentclass[preview,border=12pt,12pt]{standalone} \usepackage{amsmath} \def\f(#1){(#1)^2-5*(#1)+6} \begin{document} \section{Problem} Evaluate $\f(x)$ for $x=\frac 1 2$. \section{Solution} \immediate\write18{cas "x: 1/2;tex(\f(x));"} \input{solution} \end{document} ``` Step 4 Compile the input file with `pdflatex -shell-escape main` and you will get a nice output as follows. ! Step 5 Done. Questions Apparently the output of Maxima is as follows. I don't know how to make it cleaner. ``` solution.tex 1 - 2 $${{15}\over{4}}$$ false ``` Now, my question are - how to remove such texts? - how to obtain just `\frac{15}{4}` without `$$...$$`?
