How to convert DOM::MATRIX to Function

A simple example of what I am doing is as follows: s := t*0.2: b := matrix([0.5,0.6,0.1]): f := matrix([sin(s),cos(s),s]): X := transpose(b)*(f); plotfunc2d(X,t=-2*PI..2*PI); The error is: Error: Expecting an arithmetical expression or a function.…

MuPAD evaluation of local variables, Sum of row of array

I have discovered a strange behavior in MuPAD version 5.7.0 (MATLAB R2011b), and I would like to know whether this is a bug, and if not so, what I am doing wrong. Ideally, I would also like to know why MuPAD does what it does. Consider the array C…

Array Size in Mupad?

It seems much more clearer that be asked; but I could not find it by my first searches. Does anyone know how to find size of an array in Mupad session of Matlab? M := [12 , 21, 432]: size(M): length(M): None of them works well for me.

Use more "natural" form to manipulate piecewise step functions in Matlab MuPAD?

I have the unit step function: u0:= piecewise([-infinity < t and t < 0,0],[0 < t and t < infinity,1]): Now I want to plot it at some point: T:=1:; plot(u0|t=t-T/2); This works. But when I use a more natural expression: T:=1:; plot(u0(t-T/2)); it…

Algorithm to determine if a symbolic expression is a linear function

Is there an easy way to check if a vector valued symbolic function is linear? If so, is there an easy way to represent this expression in the form A*x, where A is a symbolic matrix and x is the argument (i.e. is there a way to "extract" A given x…
