sub_matrix_inplace_rev()

void Chusov::Math::sub_matrix_inplace_rev	(	const ValueType *	minuend_column_matrix,
		ValueType *	subtrahend_column_matrix,
		std::size_t	columns,
		std::size_t	rows
	)

Performs a subtraction of two matrices using two-dimensional array representation and writes the difference in place of the subtrahend.

Template Parameters

ValueType

A type of a matrix element.

Parameters

[in]	minuend_column_matrix	A pointer to a buffer holding the minuend matrix of columns by rows elements to subtract from.
[in,out]	subtrahend_column_matrix	A pointer to a buffer, that on input contains elements of the subtrahend which is a matrix of columns by rows elements. On output the buffer contains the result of the subtraction.
	columns	A number of columns in the matrices to subtract.
	rows	A number of rows in the matrices to subtract.

Exceptions

Any	exceptions that originate from subtraction or move-assignment of ValueType scalars.

To subtract matrices writing the difference in place of the minuend rather than the subtrahend, use sub_matrix_inplace. To write the difference to a buffer different from buffers of both of the operands, use either sub_matrix_copy, to replace some other existing matrix with the difference, or sub_matrix_construct to construct the result of addition in an uninitialized buffer.
