He asked a mxn matric tho.. Does a non-square matrix have a diagonal? hmmm.

slaaibak · Answer

Should not :/

mr.math · Answer

I don't think so. m has to be equal to n.

Maybe it's a question about determining whether or not a (m x n) matrix is in row-reduced form?  In which case my answer isn't always true, because you could have a pivot in row 1 col 1 , and another in row 2 ... col 3 or something.  

Truthfully I read it as 'n x n'. ;-p
