public class LUDecompositionAlt_DDRM extends LUDecompositionBase_DDRM

An LU decomposition algorithm that originally came from Jama. In general this is faster than what is in NR since it creates a cache of a column, which makes a big difference in larger matrices.

    • decompose

      public boolean decompose(DMatrixRMaj a)
      This is a modified version of what was found in the JAMA package. The order that it performs its permutations in is the primary difference from NR
      Parameters:
      a - The matrix that is to be decomposed. Not modified.
      Returns:
      true If the matrix can be decomposed and false if it can not.
