public abstract class CMatrixD1
extends java.lang.Object
implements CMatrix, ReshapeMatrix
A generic abstract class for matrices whose data is stored in a single 1D array of floats. The format of the elements in this array is not specified. For example row major, column major, and block row major are all common formats.
