show & scroll - Visualize arbitrary N-dimensional arrays

Visualization functions for 3D, 4D, 5D and arbitrary N-D arrays

Powerful visualization for numerical arrays of arbitrary dimensionality. Data can be 3D, 4D, 5D or arbitrary N-dimensional arrays.
Dimensions 1 and 2 are arranged as in images, dimensions 3 and 4 can be optionally tiled (see figure and see examples below), all trailing dimensions can be scrolled through using the mouse wheel and the keyboard (e.g. +/- keys for dimension 5, "a"/"q" keys for dimension 6, "s"/"w" keys for dimension 7 etc.)

Additional functionality:
* Several figure windows can be switched between using arrow keys
* Array coordinates and values can be explored using the mouse cursor
* Color axis scaling can be controlled using Shift+Mousewheel, Ctrl+Mousewheel, Ctrl+Shift+Mousewheel, Alt+Mousewheel
* Complex-valued arrays are supported (requires FileExchange submission 20292 "hsl2rgb and rgb2hsl conversion")

Examples:

% 5-D array of size 10x10x10x10x10
A=randn([10,10,10,10,10]);

show(A) % visualize using 4-D tiles
show(A,'3d') % visualize using 3-D tiles
scroll(A) % visualize using 2-D tiles

% complex-valued array
% (requires FileExchange submission 20292 "hsl2rgb and rgb2hsl conversion")
C=randn([10,10,10,10,10]).*exp(2*pi*1i*rand([10,10,10,10,10]));

show(C) % encode magnitude as brightness and complex phase as color hue
showm(C) % show magnitude only
show(C,0) % show magnitude only
show(C,1) % encode complex phase as color hue
show(C,2) % encode magnitude as colormap and phase as brightness
show(C,3) % phase only as color hue
show(C,4) % phase only as brightness
