Assigns the matrix data of one instance of XMMATRIX to the current instance of XMMATRIX and returns a reference to the current instance.

This operator assigns the matrix data of one instance of XMMATRIX to the current instance of XMMATRIX and returns a reference to the current instance.

Note This operator is only available when developing with C++.

Syntax

XMMATRIX & operator=(
  [ref] const XMMATRIX & M
) noexcept;

Parameters

[ref] M

Instance of XMMATRIX whose data is used to update the current instance.

Return value

A reference to the current instance of XMMATRIX, which has been updated by this operator.

Remarks

The following pseudocode demonstrates the operation of this operator:


XMMATRIX mat1; XMMATRIX M; // mat1=mat1*M for (int i=0;i<4;i++){ for (int j=0;j<4;j++){ mat1.m[i][j]=M.m[i][j]; } }

XMMATRIX mat1;
XMMATRIX M;
// mat1=mat1*M
for (int i=0;i<4;i++){
for (int j=0;j<4;j++){
mat1.m[i][j]=M.m[i][j];
}
}
