5.6 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. Most of the matrix
operations will also work on images.
-
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.
-
Convert to Matrix
- Try to make anything into a matrix.
-
Extract
- This group of items
extracts various submatricies. You can also do this
graphically: just drag-select an area in matrix.
-
Insert, Delete, …
- Also work on images, which can be
handy. A 45 degree rotate will only work for square
matricies with odd-length sides.
-
Invert
- Simple matrix-only maths operations.
-
Plot Scatter
- This takes a two-column matrix where the
columns are the X and Y positions of points and
draws a scatter graph.
