Interface DoubleMatrixModel

All Known Implementing Classes:

DenseDoubleMatrixModel, SparseDoubleMatrixModel

public interface DoubleMatrixModel

This interface provides methods for accessing and modifying matrices holding double floating point primitive type elements. Note that the interface does not force any sort of bounds checking. This is an implementation detail and it is encouraged that implementations of DoubleMatrixModel do the required bounds- checking. Certain high-performance code does not do any bounds-checking in order to speed up the computation process and this is allowed, but discouraged.
