Matrix Parsing/Evaluation Bug

[rdbyk]

Describe the bug

An expression "[ ... ]" to create a matrix, which contains variables throws an error and does
not create the matrix as expected.

To Reproduce

A=[a a a; b b b; c c c]

Expected behavior

Matrix A should be be created without error.

Temp workaround:

 A=[a, a, a; b, b, b; c, c, c]

Case OK:

 A=[a, a, a]
A = [a a  ;a  -a] 
[a a  ; -a  a] 
[a a; a (a)]

Case KO:

 A=[a a; a a]

Ok, thanks!

matlab also allow: A=[-0.095-0.021j,-1]
