WebDec 19, 2014 · The concept of nonsingular matrix is for square matrix, it means that the determinant is nonzero, and this is equivalent that the matrix has full-rank. Cite. 25th Apr, 2014. Zhijun Zhang. In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate), if there exists an n-by-n square matrix B such that where In denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case, then the matrix B is uniquely determined by A, and is called the (multiplicative) inverse of A, denoted by A . Matrix inversion is the process of finding the matrix …
