      • viewColumn

        public DComplexMatrix2D viewColumn(int column)
        Description copied from class: DComplexMatrix3D
        Constructs and returns a new 2-dimensional slice view representing the slices and rows of the given column. The returned view is backed by this matrix, so changes in the returned view are reflected in this matrix, and vice-versa.

        To obtain a slice view on subranges, construct a sub-ranging view ( view().part(...)), then apply this method to the sub-range view. To obtain 1-dimensional views, apply this method, then apply another slice view (methods viewColumn, viewRow) on the intermediate 2-dimensional view. To obtain 1-dimensional views on subranges, apply both steps.

        Overrides:
        viewColumn in class DComplexMatrix3D
        Parameters:
        column - the index of the column to fix.
        Returns:

Indexes can occur multiple times and can be in arbitrary order.

        Note that modifying the index arguments 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.

        viewSelection in class DComplexMatrix3D
        Parameters:
        sliceIndexes - The slices of the cells that shall be visible in the new view. To indicate that all slices shall be visible, simply set this parameter to null.
