QM_SetIdentityMatrix

QM_SetIdentityMatrix(matrixRec):error
	matrixRec	Array real	Matrix record
	error	Longint	Error result

Sets the contents of a matrix record to the identity matrix. The identity matrix does not perform an tranformations.

Parameter matrixRec receives the identity matrix. It must be declared as a 3 x 3 array of reals.

Example

ARRAY REAL($matrix;3;3)

$err:=QM_SetIdentityMatrix ($matrix)
