construct_diagonal_matrix()

void Chusov::Math::construct_diagonal_matrix ( ValueType *  column_matrix, std::size_t  columns, std::size_t  rows, ValueType  diag  )

noexcept

Constructs a diagonal column-major matrix in a specified buffer.

Template Parameters

ValueType

A type of a matrix element.

Parameters

[out]	column_matrix	A buffer which receives the constructed matrix. The array must be sufficient to hold columns * rows elements of the type ValueType.
	columns	A number of columns in the matrix to create.
	rows	A number of rows in the matrix to create.
	diag	A value copy-constructed in places of the main diagonal of column_matrix.

Exceptions

Any	exception thrown by the default, copy or move constructors of ValueType.

Unlike construct_diagonal_matrix, this function performs inplace coopy-construction rather than copy-assignment of the elements.
