All Implemented Interfaces:

java.io.Serializable
```
public class GMatrixd
extends java.lang.Object
implements java.io.Serializable
```
Matrix operations are applied on the left. For example, given a matrix M and a vector V, matrix-times-vector is M*V. That is, V is treated as a column vector. Some graphics APIs use V*M where V is treated as a row vector. In this context the "M" matrix is really a transpose of the M as represented in Wild Magic. Similarly, to apply two matrix operations M0 and M1, in that order, you compute M1*M0 so that the transform of a vector is (M1*M0)*V = M1*(M0*V). Some graphics APIs use M0*M1, but again these matrices are the transpose of those as represented in Wild Magic. You must therefore be careful about how you interface the transformation code with graphics APIS. Matrices are stored in row-major order, matrix[row][col].
