Method Detail

getMBDict

public final MatrixBlockDictionary getMBDict(int nCol)

Description copied from interface: IDictionary

Get this dictionary as a MatrixBlock dictionary. This allows us to use optimized kernels coded elsewhere in the system, such as matrix multiplication. Return null if the matrix is empty.

Specified by:

getMBDict in interface IDictionary

Overrides:

getMBDict in class ADictionary

Parameters:

nCol - The number of columns contained in this column group.

Returns:

A Dictionary containing a MatrixBlock.
