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.
