MuPAD is a computer algebra system.
MuPAD is the computer algebra system behind the Symbolic Math Toolbox for MATLAB. It is not sold separately, but does offer a more symbolic computation oriented language as an alternative to computing in MATLAB.

Rewriting a function in specific terms with Matlab
I feel there should be an easy solution to my problem but I couldn't find it.
I can explain my problem through a very simple example:
Given the functions f and a:
f := x(x-3) + 2x(x-3)
a := (x-3)
I now want to write f in terms of a which should…

Error messege about identifiers in mupad procedures
I try to write functions in mupad but it seems I haven't understood how procedures and identifiers work. I get every time the message "Error: Unexpected 'identifier'". First example: I tried changing the first row of a given matrix to [1 1 ... 1].…

Mupad 3D graphing issues
I have been trying to plot two surfaces on a 3D graph using Mupad.
The first is created by the function:
(x-1)^2 / 4 + (y+2)^2 / 9 + (z+1)^2 = 9
The Second surface I have no problems with apart from some scaling issues:
4(x-1)^2 + 4(y+2)^2 =…

Matlab: ratio of symbolic polynomials - extract numerator and denominator
Suppose I have a Matlab expression consisting of a ratio of polynomials of the symbolic variable 'x'. The polynomial coefficients are likewise symbolic. Is there a simple way to extract the numerator and the denominator of the expression? It is fine…

Is this a bug in MuPAD?
I have u0 as step function (piecewise definition):
piecewise([0 < t, 1], [t < 0, 0])
Now I compute:
int(u0(t)|t=k, k=-infinity..t)
which gives
piecewise([0 < t, t], [t <= 0, 0])
In a textbook I found the answer:
piecewise([0 =< t, t], [t < 0,…

How to translate this code from muPAD to Python?
I hope if someone knows how to express the following Mupad code in Python:
for n from 1 to 6 do
M:= matrix([[B(k,j) $ k = 0..n] $ j = 0..n]);
C:=matrix([c(j)$ j = 0..n]);
A:=linalg::matlinsolve(M, C);P:=sum(A[j+1]*x^j, j = 0..n);plot(P,fx, x…
