Test matrix for singularity.
Syntax: @issingular(m)
m: matrix, sym
Return: integer
Returns “1” if the square matrix or sym, m, is singular, and “0” otherwise.
A singular matrix has a determinant of 0, and cannot be inverted.
Examples
matrix m1 = @mnrnd(1, 10)
sym s1 = @inner(m1)
= @issingular(s1)
returns 1 indicating that the inner product of M1 is singular (i.e., not invertible).
