| _ij |
An array of floats that represent a 4x4 matrix, where i is the row number and j is the column number. For example, _34 means the same as [a₃₄], the component in the third row and fourth column. |
Remarks
In Direct3D, the _34 element of a projection matrix cannot be a negative number. If your application needs to use a negative value in this location, it should scale the entire projection matrix by -1 instead.
