      • zero

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

      • set

        public void set​(float a1,
                float a2,
                float a3,

      • get

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

      • unsafe_get

        public float unsafe_get​(int row,
                        int col)
        Description copied from interface: FMatrix
        Same as FMatrix.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 FMatrix
        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,
                float val)
        Description copied from interface: FMatrix
        Sets the value of the specified matrix element.
        Specified by:
        set in interface FMatrix
        Parameters:
        row - Matrix element's row index..
        col - Matrix element's column index.
        val - The element's new value.

      • unsafe_set

                       float val)
        Description copied from interface: FMatrix
        Same as FMatrix.set(int, int, float) 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 FMatrix
        Parameters:
