Method Detail

outer

public static void outer(org.ejml.data.FMatrix1Row a,
                         org.ejml.data.FMatrix1Row c)

inner_small

public static void inner_small(org.ejml.data.FMatrix1Row a,
                               org.ejml.data.FMatrix1Row c)

inner_reorder

public static void inner_reorder(org.ejml.data.FMatrix1Row a,
                                 org.ejml.data.FMatrix1Row c)

inner_reorder_upper

public static void inner_reorder_upper(org.ejml.data.FMatrix1Row a,
                                       org.ejml.data.FMatrix1Row c)

inner_reorder_lower

public static void inner_reorder_lower(org.ejml.data.FMatrix1Row A,
                                       org.ejml.data.FMatrix1Row B)

Computes the inner product of A times A and stores the results in B. The inner product is symmetric and this function will only store the lower triangle. The value of the upper triangular matrix is undefined.

B = A^T*A

Parameters:

A - (Input) Matrix

B - (Output) Storage for output.
