Converting inputdlg entries to symbols in a matrix

Code for non-symbol case:
Matrices = inputdlg({'Matrix 1', 'Matrix 2'})
Matrix1 = str2num(Matrices{1})
Matrix2 = str2num(Matrices{2})
Product = Matrix1*Matrix2
I have tried the following but it does not work.
str2sym(Matrices{1})
I want the user to be able to enter somethig like a 40; c 20 and have this converted to a matrix whilst recognising the letters as symbolic values.

You need to have [] around the entries. str2sym() will not assume that a space is to indicate a list.
Matrices = {'40', 'c 20'}
str2sym(Matrices{1})
str2sym("["+ Matrices{2}+"]")
