// Matrix should be the active window
void MatrixLayer_MatrixLayer_Ex3()
{
    MatrixLayer mlay(Project.ActiveLayer());
    if(!mlay)
    {
        out_str("The active layer is not a matrix, or there is nothing in the project");
    }

}

Remark

MatrixLayer is one of the wrapper objects that is a reference to the actual internal Origin object.

You can construct a new MatrixLayer from another layer object. The MatrixLayer will become invalid if the layer to construct with is actually not an object of Matrix class in Origin.
