Q3Matrix3x3_SetIdentity

You can use the Q3Matrix3x3_SetIdentity function to set a 3-by-3 matrix to the identity matrix.

TQ3Matrix3x3 *Q3Matrix3x3_SetIdentity (TQ3Matrix3x3 *matrix3x3);

matrix3x3

On exit, the 3-by-3 identity matrix.

DESCRIPTION

The Q3Matrix3x3_SetIdentity function returns, as its function result and in the matrix3x3 parameter, the 3-by-3 identity matrix.
