19 Oct 2012 Patchline Visualize lines as patch objects. Specify any valid patch property, including transparency. Author: Brett Shoelson

This is pretty useful.

To enable it to handle a matrix of y-values (column-wise) I made the following change which you may like to incorporate:

ADDED AFTER LINE 97 ("% Facecolor = 'k' is (essentially) ignored"...)
%Make x-vector the same size as y-matrix (assuming data is in columns)
if size(ys,2)>1 && size(xs,2)==1
xs = repmat(xs,1,size(ys,2));
end
%Add NaNs onto bottom row (so it doesn't plot an area?)
xs = [xs; NaN(1, size(xs,2))];
ys = [ys; NaN(1, size(ys,2))];
% Plot the "patches" (actually lines)
if isempty(zs)
p = patch(xs, ys, 'w');
else
p = patch(xs, ys, zs, 'w');
end

THE ABOVE REPLACED:
% if isempty(zs)
% p = patch([xs(:);NaN],[ys(:);NaN],'k');
% else
% p = patch([xs(:);NaN],[ys(:);NaN],[zs(:);NaN],'k');
% end

16 Jun 2011 Arrow plotter very simple customizable inline function to draw arrows. Author: Ryan Molecke

Nice and simple. Works OK if the xlimits and ylimits are across similar ranges. In such cases, or where plotting will be similar each call, this should be great. Otherwise the arrowhead shape is a bit unpredictable due to distortion.

I ended up going back to arrow.m (by Erik A. Johnson, it is on the file exchange. Yes that does look like a monster, at nearly 1400 lines!).

31 May 2011 Structure outline Prints the hierarchy outline of a structure with optionally, field values. Author: B.

Worked for me.
16 Nov 2010 readtext Any text (file) you give it, readtext returns an array of the contents. You can chose delimiter etc. Author: Peder Axensten

This is really useful to me and I have used it quite a bit.

I noticed however that comment lines are not fully removed but instead leave a blank line (apart from the very first line which will be fully removed if it is a comment). My work-around is shown below (although it has the downside of removing ALL blank lines - whether commented or not).

Replace the following lines:
if(~isempty(opts.comment)) % Remove comments.
text= regexprep(text, ['^\' opts.comment '[^' eol ']*' eol], '');
text= regexprep(text, [ '\' opts.comment '[^' eol ']*'], '');
end

with these lines:
if(~isempty(opts.comment)) % Remove comments.
text= regexprep(text, ['\' opts.comment '[^' eol ']*'], ''); % Remove commented line endings (but in the case of whole-lines this leaves a blank line!).
text= regexprep(text, [eol '+'], eol); % Remove blank lines, part 1: remove multiple eol instances (2 in a row = a blank line)
text= regexprep(text, ['^' eol '+'], ''); % Remove blank lines, part 2: if there is an eol at the beginning then remove it.
end
