XMMATRIX::operator()(size_t,size_t) function (directxmath.h)

Returns a reference to a matrix element of an instance XMMATRIX as specified by row and column arguments.

This operator returns a reference to a matrix element of an instance XMMATRIX as specified by row and column arguments.

Syntax

float & operator()(
  size_t Row,
  size_t Column
) noexcept;

Parameters

Row

Row containing the matrix element of interest. Row specification is 0 based.

Column

Column containing the matrix element of interest. Column specification is 0 based.

Return value

A reference to the matrix element specified by the operator's Row and Column arguments.

Remarks

This operator is only available when building with _XM_NO_INTRINSICS_.

As a reference to the matrix element is returned, this operator can be used to update the value of an element of an instance of XMMATRIX.

The following example:

     XMMATRIX mat;
     float& a= mat(1,2);
     a=42.0;
