Singular matrix

For example, we say a 'two by two matrix,' but we Definition of singular matrix, from the Stat Trek dictionary of statistical terms and concepts. This statistics glossary includes definitions of all technical terms used A square matrix, A, of numbers whose determinant is zero. A is singular if and only if it is not invertible (see inverse matrix). Matrix is singular to working precision. RCOND=NaN. What can I do to avoid this and make the operation?

What is a singular matrix? The definition of a singular matrix, also known as a degenerate matrix, is as follows: A singular (or degenerate) matrix is a square matrix whose inverse matrix cannot be calculated.

If "the matrix is close to singular or badly scaled", the coefficient matrix (A) is most likely ill-conditioned.This means that the condition number of the matrix is considerable.
