AnalysisLibErrType GenInvMatrix (void *inputMatrix, int matrixSize, int matrixType, void *matrixInverse);
Calculates the inverse of the real, square input matrix.
If B denotes the inverse of the matrix A, then
AB = I
where I is the identity matrix
In contrast to InvMatrix, GenInvMatrix allows you to specify the type of the input matrix with the matrixType parameter. The input matrix can be an upper or lower triangular matrix, a general square matrix, or a positive definite matrix. You can save significant computation time if you properly specify the type of the matrix.
Input | ||||||||||||
Name | Type | Description | ||||||||||
inputMatrix | numeric array | Input square matrix. This matrix must be an array of doubles. | ||||||||||
matrixSize | integer | Number of elements in one dimension of the input matrix. | ||||||||||
matrixType | integer | Type of the matrix. Choose the matrix type correctly because it significantly affects the speed of computation. The following table lists the valid matrixType values.
