      • getQuick

        public double[] getQuick(int index)
        Description copied from class: DComplexMatrix1D
        Returns the matrix cell value at coordinate index.

        Provided with invalid parameters this method may return invalid objects without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): index<0 || index>=size().

        Specified by:
        getQuick in class DComplexMatrix1D
        Parameters:
        index - the index of the cell.
        Returns:
        the value of the specified cell.
      • like

        public DComplexMatrix1D like(int size)
        Description copied from class: DComplexMatrix1D
        Construct and returns a new empty matrix of the same dynamic type as the receiver, having the specified size. For example, if the receiver is an instance of type DenseDComplexMatrix1D the new matrix must also be of type DenseDComplexMatrix1D. In general, the new matrix should have internal parametrization as similar as possible.
        Specified by:
        like in class DComplexMatrix1D
        Parameters:
        size - the number of cell the matrix shall have.
        Returns:
        a new empty matrix of the same dynamic type.
      • like2D

        public DComplexMatrix2D like2D(int rows,                      int columns)
        Description copied from class: DComplexMatrix1D
        Construct and returns a new 2-d matrix of the corresponding dynamic type, entirely independent of the receiver. For example, if the receiver is an instance of type DenseDComplexMatrix1D the new matrix must be of type DenseDComplexMatrix2D.

      • setQuick

        public void setQuick(int index,            double[] value)
        Description copied from class: DComplexMatrix1D
        Sets the matrix cell at coordinate index to the specified value.

        Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): index<0 || index>=size().

        Specified by:
        setQuick in class DComplexMatrix1D
        Parameters:
        index - the index of the cell.
        value - the value to be filled into the specified cell (re=value[0], im=value[1]).
      • setQuick

        public void setQuick(int index,            double re,            double im)
        Description copied from class: DComplexMatrix1D
        Sets the matrix cell at coordinate index to the specified value.

        Provided with invalid parameters this method may access illegal indexes without throwing any exception. You should only use this method when you are absolutely sure that the coordinate is within bounds. Precondition (unchecked): index<0 || index>=size().

        Specified by:
        setQuick in class DComplexMatrix1D
        Parameters:
        index - the index of the cell.
        re - the real part of the value to be filled into the specified cell.
        im - the imaginary part of the value to be filled into the specified cell.
      • viewFlip

        public DComplexMatrix1D viewFlip()
        Description copied from class: DComplexMatrix1D
        Constructs and returns a new flip view. What used to be index 0 is now index size()-1, ..., what used to be index size()-1 is now index 0. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa.
        Overrides:
        viewFlip in class DComplexMatrix1D
        Returns:
        a new flip view.
      • viewPart

        public DComplexMatrix1D viewPart(int index,                        int width)
        Description copied from class: DComplexMatrix1D
        Constructs and returns a new sub-range view that is a width sub matrix starting at index. Operations on the returned view can only be applied to the restricted range. Any attempt to access coordinates not contained in the view will throw an IndexOutOfBoundsException.

        Note that the view is really just a range restriction: The returned matrix is backed by this matrix, so changes in the returned matrix are reflected in this matrix, and vice-versa.

        The view contains the cells from index..index+width-1. and has view.size() == width. A view's legal coordinates are again zero based, as usual. In other words, legal coordinates of the view are 0 .. view.size()-1==width-1. As usual, any attempt to access a cell at other coordinates will throw an IndexOutOfBoundsException.

        Overrides:
        viewPart in class DComplexMatrix1D
        Parameters:
        index - The index of the first cell.
        width - The width of the range.
        Returns:
        the new view.
      • viewSelection

        public DComplexMatrix1D viewSelection(int[] indexes)
        Description copied from class: DComplexMatrix1D
        Constructs and returns a new selection view that is a matrix holding the indicated cells. There holds view.size() == indexes.length and view.get(i) == this.get(indexes[i]). Indexes can occur multiple times and can be in arbitrary order. Note that modifying indexes after this call has returned has no effect on the view. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa.
        Overrides:
        viewSelection in class DComplexMatrix1D
        Parameters:
        indexes - The indexes of the cells that shall be visible in the new view. To indicate that all cells shall be visible, simply set this parameter to null.
        Returns:
        the new view.
      • viewStrides

        public DComplexMatrix1D viewStrides(int _stride)
        Description copied from class: DComplexMatrix1D
        Constructs and returns a new stride view which is a sub matrix consisting of every i-th cell. More specifically, the view has size this.size()/stride holding cells this.get(i*stride) for all i = 0..size()/stride - 1.
        Overrides:
        viewStrides in class DComplexMatrix1D
        Parameters:
        _stride - the step factor.
        Returns:
        the new view.
