I can't figure out why Mathematica can't calculate rank of a symbolic matrix. Please take a look at the attached screenshot below.
If you need the full source code then you can find it in the "z_x_expression.nb" file via the link.
What am I doing wrong?
MatrixForm. Remove it from the definition ofA. Also, please provide copy-pastable code instead of screenshots to help users help you. – anderstood Mar 04 '18 at 15:08
