.SH NAME
FcMatrixRotate \- Rotate a matrix
.SH SYNOPSIS
.sp
\fB#include <fontconfig/fontconfig.h>
.sp
void FcMatrixRotate (FcMatrix *\fImatrix\fB, double \fIcos\fB, double \fIsin\fB);
\fR
.SH "DESCRIPTION"
.PP
\fBFcMatrixRotate\fR rotates \fImatrix\fR
by the angle who's sine is \fIsin\fR and cosine is
\fIcos\fR\&.  This is done by multiplying by the
matrix:

.nf
  cos -sin
  sin  cos
