How to Calculate the Inverse of a Matrix - AcademicHelp.net
WEBJan 31, 2024 · The inverse of a matrix, often denoted as Matrix A^{-1}, is a unique matrix that, when multiplied with the original matrix, yields the identity matrix. This process, known as matrix inversion, is akin to finding the reciprocal of a number in basic arithmetic.
inv (MATLAB Function Reference) - Mathematics
WEBY = inv(X) returns the inverse of the square matrix X. A warning message is printed if X is badly scaled or nearly singular. In practice, it is seldom necessary to form the explicit inverse of a matrix.
