Question

What are singular and non singular matrix

Answer 1

Singular Matrix. A square matrix that does not have a matrix inverse. A matrix is singular iff its determinant is 0. For example, there are 10 singular (0,1)-matrices: The following table gives the numbers of singular matrices for certain matrix classes.

A square matrix that is not singular, i.e., one that has a matrix inverse. Nonsingular matrices are sometimes also called regular matrices. A square matrix is nonsingular iff its determinant is nonzero
