5.7 Matrix

This menu groups operations which operate on matricies. `nip2` has four ways of displaying a matrix, but they all behave in the same way under the skin. Almost all the items in the `Math` menu will work on matricies.

`New`
  The first four items make matricies which display and edit in various ways useful for different applications. The final two make matricies which are pre-filled with useful numbers.

`Extract`
  This group of items add and remove rows and columns, and rotates and flips. A 45 degree rotate will only work for square matricies with odd-length sides.

`Invert`
  Simple matrix-only maths operations.

`Matrix to Image`
  Convert between images and matricies. This will only work for small images: it is very inefficient to represent an image as a matrix.

`Plot Scatter`
  This takes a two-column matrix where the columns are the X and Y positions of points and draws a scatter graph.
