java.lang.Object
org.ejml.dense.row.mult.MatrixMultProduct_DDRM
public class MatrixMultProduct_DDRM extends Object

Specialized operations for performing inner and outer products for matrices.

inner product: B=AT*A
outer product: B=A*AT

      public MatrixMultProduct_DDRM()

  • Method Details

    • outer

      public static void outer(DMatrix1Row a, DMatrix1Row c)

    • inner_small

      public static void inner_small(DMatrix1Row a, DMatrix1Row c)

    • inner_reorder

      public static void inner_reorder(DMatrix1Row a, DMatrix1Row c)

    • inner_reorder_upper

      public static void inner_reorder_upper(DMatrix1Row a, DMatrix1Row c)

    • inner_reorder_lower

      public static void inner_reorder_lower(DMatrix1Row A, DMatrix1Row 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 = AT*A

      Parameters:
      A - (Input) Matrix
      B - (Output) Storage for output.
