Can MATLAB show the dimensions of matrices when outputting a dimension mismatch error?

Can MATLAB show the dimensions of matrices when outputting a dimension mismatch error?

MATLAB currently has no feature to output the dimensions of incompatible matrices whose operator triggers a dimension mismatch error.  The following error message cannot be generated by MATLAB:

>> A = ones(88, 32);
>> B = ones(33, 99);
>> X = A*B;

Error using  * 

Inner matrix dimensions must agree.

A has a dimension of (r1, c1) = (88, 32)

B has a dimension of (r2, c2) = (33, 99)

c1 must be equal to r2

Instead, the following error message is standard:

>> A = ones(88, 32);

>> B = ones(33, 99);

>> X = A*B;

Error using  * 

Inner matrix dimensions must agree.
