    • mult

      public static void mult(org.ejml.data.FMatrixSparseCSC A, org.ejml.data.FMatrixSparseCSC B, org.ejml.data.FMatrixSparseCSC C, @Nullable @Nullable org.ejml.data.IGrowArray gw, @Nullable @Nullable org.ejml.data.FGrowArray gx)
      Performs matrix multiplication. C = A*B
      Parameters:
      A - Matrix
      B - Matrix
      C - Storage for results. Data length is increased if increased if insufficient.
      gw - (Optional) Storage for internal workspace. Can be null.
      gx - (Optional) Storage for internal workspace. Can be null.

    • multAddColA

      public static void multAddColA(org.ejml.data.FMatrixSparseCSC A, int colA, float alpha, org.ejml.data.FMatrixSparseCSC C, int mark, float[] x, int[] w)
      Performs the operation x = x + A(:,i)*alpha

      NOTE: This is the same as cs_scatter() in csparse.

    • addRowsInAInToC

      public static void addRowsInAInToC(org.ejml.data.FMatrixSparseCSC A, int colA, org.ejml.data.FMatrixSparseCSC C, int colC, int[] w)
      Adds rows to C[*,colC] that are in A[*,colA] as long as they are marked in w. This is used to grow C and colC must be the last filled in column in C.

      NOTE: This is the same as cs_scatter if x is null.

      Parameters:
      A - Matrix
      colA - The column in A that is being examined
      C - Matrix
      colC - Column in C that rows in A are being added to.
      w - An array used to indicate if a row in A should be added to C. if w[i] < colC AND i is a row in A[*,colA] then it will be added.
