public float[] getQuick(int index)
FComplexMatrix1D
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().

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().

- the value to be filled into the specified cell (re=value[0],
im=value[1]).public void setQuick(int index, float re, float im)

setQuick
in class FComplexMatrix1D
index

public FComplexMatrix1D viewPart(int index, int width)
FComplexMatrix1D
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

index
- The index of the first cell.width
- The width of the range.
