Figure to Simulink subsystem mask icon converter

Creates a mask icon for a Simulink subsystem from a given figure. This subsystem is masked with a ICON correspoding to lines in the figure. This is useful to illustrate the behaviour of the subsystem by a icon.

You can use the simplot command to create it from the actual output. See the documentation of simplot (doc simplot) for further info.

FUNCTION:
function fig2simulinkmaskicon(hFig,colors)

INPUTS:
hFig - handle to a figure to be used (e.g. gcf)
colors - (OPTIONAL) colors for different lines.

Supported (default) colors: blue, red, green, magenta, yellow, cyan, black

OUTPUTS:
Creates a simulink subsystem with a given mask
Prints out the Mask/Icon string in the command window.

Example:
h = figure; hold on;
plot([0:0.1:10],sin([0:0.1:10]));
plot([0:0.5:12],cos([0:0.5:12]));
fig2simulinkmaskicon(gcf);
fig2simulinkmaskicon(gcf,'yellow');
fig2simulinkmaskicon(gcf,{'red','magenta'});
