Matrix4D::GetRow

Defined in: C4Matrix4D.h

Returns a Vector4D object containing the entries of a particular row.

Prototype

Vector4D GetRow(long i) const;

Parameters

`i`	The index of the row. This must be 0, 1, 2, or 3.

Description

The GetRow function returns a vector containing the four entries in the row specified by the i parameter. Since matrices are stored in column-major order, this function must copy the entries into a new Vector4D object. A reference to a column of a matrix, requiring no copy, can be retrieved using the [] operator.
