> ## Name

> cgSetMatrixParameter - sets the value of matrix parameters

> ## Synopsis

>     #include <Cg/cg.h>

>     /* TYPE is int, float or double */

>     void cgSetMatrixParameter{ifd}{rc}( CGparameter param,
>                                         const TYPE * matrix );

> ## Parameters

> param
>   The parameter that will be set.
> matrix
>   An array of values to which to set the matrix parameter. The array must be the number of rows times the number of columns in size.

> ## Return Values

> None.

> ## Description

> The cgSetMatrixParameter functions set the value of a given matrix parameter. The functions are available in various combinations.

> There are versions of each function that take int, float or double values signified by the i, f or d in the function name.

> There are versions of each function that assume the array of values are laid out in either row or column order signified by the r or c in the function name respectively.

> The cgSetMatrixParameter functions may only be called with uniform parameters.

> ## Examples

> to-be-written

> ## Errors

> CG_NOT_MATRIX_PARAM_ERROR is generated if param is not a matrix parameter.

> CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

> CG_INVALID_PARAMETER_ERROR is generated if the parameter fails to set for any other reason.

> ## History

> The d and f versions of cgSetMatrixParameter were introduced in Cg 1.2.

> The i versions of cgSetMatrixParameter were introduced in Cg 1.4.
