    • zero

      public void zero()
      Description copied from interface: Matrix
      Sets all values inside the matrix to zero
      Specified by:
      zero in interface Matrix

    • setTo

      public void setTo(double a1, double a2)

    • setTo

      public void setTo(int offset, double[] array)

    • get

      public double get(int row, int col)
      Description copied from interface: DMatrix
      Returns the value of value of the specified matrix element.
      Specified by:
      get in interface DMatrix
      Parameters:
      row - Matrix element's row index..
      col - Matrix element's column index.
      Returns:
      The specified element's value.

    • unsafe_get

      public double unsafe_get(int row, int col)
      Description copied from interface: DMatrix
      Same as DMatrix.get(int, int) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.
      Specified by:
      unsafe_get in interface DMatrix
      Parameters:
      row - Matrix element's row index..
      col - Matrix element's column index.
      Returns:
      The specified element's value.

    • set

      public void set(int row, int col, double val)
      Description copied from interface: DMatrix
      Sets the value of the specified matrix element.
      Specified by:
      set in interface DMatrix
      Parameters:
      row - Matrix element's row index..
      col - Matrix element's column index.
      val - The element's new value.

    • unsafe_set

      public void unsafe_set(int row, int col, double val)
      Description copied from interface: DMatrix
      Same as Matrix.setTo(org.ejml.data.Matrix) but does not perform bounds check on input parameters. This results in about a 25% speed increase but potentially sacrifices stability and makes it more difficult to track down simple errors. It is not recommended that this function be used, except in highly optimized code where the bounds are implicitly being checked.
      Specified by:
      unsafe_set in interface DMatrix
      Parameters:
      row - Matrix element's row index..
      col - Matrix element's column index.
      val - The element's new value.
