InverseMatrix

The InverseMatrix function creates a new matrix that is the inverse of a specified matrix.

pascal Boolean InverseMatrix (MatrixRecord *m, 
                              MatrixRecord *im);

m

Contains a pointer to the source matrix for the operation.

im

Contains a pointer to a matrix structure that is to receive the new matrix. The InverseMatrix function updates this structure so that it contains a matrix that is the inverse of that specified by the m parameter.

DESCRIPTION

The InverseMatrix function returns a Boolean value that indicates whether it could create an inverse matrix. If the function could create an inverse matrix, it sets this returned value to true. Otherwise, the function sets the returned value to false.
