I have n symbolic expressions in terms of , which are of the variable type 'sym' in matlab. They form a system of equations that is linear in , but the symbolic expressions are NOT organized with only one term of each from how a linear system normally is.
How do I organize the system like a simplified linear system ususally looks, with only one term of each variable in each equation? I already tried the 'Simplify Symbolic Expressions' page from MATLAB and it wasn't helpfull.

Ran in:
Example:
syms x y z tau
eqns = [x+y-2*z*tau == 0,
x+y*tau^2+z == 1,
2*y-z == -5];
[A,b] = equationsToMatrix(eqns, [x, y, z])
A = 
b = 
The variables that the system is linear in must be passed as the second parameter.
