- \param rtype The output matrix data type. When it is =-1, the output array will have the same data type as (*this)
- \param alpha The scale factor
- \param beta The optional delta added to the scaled values before the conversion
+ @param [out] m - output matrix; if it does not have a proper size or type before the operation,
+ it is reallocated
+ @param [in] rtype – desired output matrix type or, rather, the depth since the number of channels
+ are the same as the input has; if rtype is negative, the output matrix will have the
+ same type as the input.
+ @param [in] alpha – optional scale factor
+ @param [in] beta – optional delta added to the scaled values
