How to change line thickness of a line (implicit_plot) in maxima [v5.44]?
I want to change the line width of a plot.
The [style, [lines, 8, 1]] option does not change the thickness. why is that?
I'm just typing it like so:
wximplicit_plot(y^2 = 4*(1/8)*x, [x, -5, 10],[y, -10, 10], [yx_ratio, 1], [xtics, -4, 1, 10],…

How to find a polynomial as an approximate solution to a nonlinear equation?
For my small FLOSS project, I want to approximate the Green et al. equation for maximum shear stress for point contact:
that should looks like this when plotted
the same equation in Maxima:

(wx)Maxima: return expressions using `sec` `csc` and `cot` instead of reciprocals?
Currently, the output for inputs involving sec or the other reciprocal trig functions seem to return expressions in terms of reciprocals, e.g.:
expand(integrate(6*sec(2*y)^7*tan(2*y)^3, y));
> 1/(3*cos(2*y)^9)\-3/(7*cos(2*y)^7)
Is there any way to…

(wx)Maxima: how to get consistent expressions using `args`?
I'm trying to write a small script that will look at the first term of an expression and determine whether it is positive or negative, then print a + or - in front of that expression, accordingly; however, I'm having a bit of trouble writing it in…

(wx)Maxima: does `makelist` work in parallel or serially?
I am interested in creating a list whose terms are defined recursively (i.e. term[i] is a function of term[i-1], not a function of i-1).
I figured that if makelist works serially, then calling a previous term should not be an issue; however, the…

Apply function to a list of named arguments in Maxima
For problems with, say, Lagrangian multipliers, you can solve for critical points. Often, you will get a set of critical points. Is there a way to easily map the original function over the solutions to evaluate/apply the function at those…

(wx)Maxima: texput for powers of expressions
I have used texput to set the tex1 output of log(x) to be \ln(x) with
texput('log, lambda([e],[a]:args(e), printf(false, "\\ln(~a)", tex1(a))));
and am wondering if it is possible to also set the output for something like (log(x))^n? In particular…

(wx)Maxima: how to iterate an action over every member of a list?
I'm wondering if there is a functional way to apply an action to every element of list, in Maxima, without necessarily looping over the list?
e.g. if I would like to remove every element of the list a:[1,2,3] from the list b:[5,4,3,2,1]. Obviously,…

Maxima add current loop iteration to filename
I have code similar to the one below, where a function with a parameter depending on the loop iteration is plotted after every iteration. I would like to save the plot with the name trigplot_i.ps where i is the iteration number, but don't know…

wxMaxima: how to use texput to tell tex1 how to handle strings?
tex1() seems to return all strings as follow:
tex1(hello);
{\it hello}
tex1("hello");
\mbox{ hello }
What variable must one use to change this handling via texput? e.g. if I would just like it to print strings literally? I'm using other…

wxMaxima: treat division as multiplication (gather overall divisions as multiplicative factor)
I'm wondering if there is any way to tell Maxima to return
1/2*x
instead of
x/2
I'm trying to handle u-substitutions using changevar however, it's returning expressions like:
\frac{\int \cos{u} \de{u}}{5}
whereas I'd like to have it display…

Maxima: how to distinguish between a row of a matrix and a row vector?
I'd like to build a function that can take a vector (i.e. a 1xm or nx1 matrix) or a column / row of a matrix, as input; however, I've come up on something that seems a bit weird: even though maxima handles vectors as matrices with either 1 row or…

Maxima: Force a function to run with local-variables only? / How to Avoid Local Operations Affecting Global-Variables?
I've just discovered that I have some basic misunderstanding about how block works for functions.
In general, I thought "what happens in a function, stays in a function (unless returned);" however, this doesn't seem to be the case, so I was hoping…

simple input of diacritical marks, and superscripts
There are times when you need to input modified variables with diacritical marks, or superscripts.
Seems like declare_index_properties allows doing it at the stage of display print.
But it is neither simple, nor very useful in formulas.
is there a…
