public long getQuick(int 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().

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.
viewPart in class LongMatrix1Dindex - The index of the first cell.width - The width of the range.IndexOutOfBoundsException - if index<0 || width<0 || index+width>size().public LongMatrix1D viewSelection(int[] indexes)
Example:
this = (0,0,8,0,7)
indexes = (0,2,4,2)
-->
view = (0,8,7,8)
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.viewSelection in class LongMatrix1Dindexes - 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.IndexOutOfBoundsException - if !(0 <= indexes[i] < size()) for any
i=0..indexes.length()-1.public LongMatrix1D viewStrides(int _stride)
viewStrides in class LongMatrix1D_stride - the step factor.IndexOutOfBoundsException - if stride <= 0.Jump to the Parallel Colt Homepage
