glMultMatrixf function
The glMultMatrixd and glMultMatrixf functions multiply the current matrix by an arbitrary matrix.
Syntax
void WINAPI glMultMatrixf( const GLfloat *m );
Parameters
 m

A pointer to a 4x4 matrix stored in columnmajor order as 16 consecutive values.
Return value
This function does not return a value.
Error codes
The following error code can be retrieved by the glGetError function.
Name  Meaning 


The function was called between a call to glBegin and the corresponding call to glEnd.

Remarks
The glMultMatrix function multiplies the current matrix by the one specified in m. That is, if M is the current matrix and T is the matrix passed to glMultMatrix, then M is replaced with M • T.
The current matrix is the projection matrix, modelview matrix, or texture matrix, determined by the current matrix mode (see glMatrixMode).
The m parameter points to a 4x4 matrix of singleprecision or doubleprecision floatingpoint values stored in columnmajor order. That is, the matrix is stored as shown in the following image.
