31 Jul 2013 Check4updates Check4updates tracks updates of your favourite FeX packages, with GUI-selection for download. Author: Bjorn Gustavsson

I managed to insert a new bug. Update on its way, for those that prefer to fix it now lines 287-288:
iCBstop = findstr(cMSG,'}');
iBS = findstr(cMSG,'\');
should be replaced with:
iCBstop = findstr(cMSG,'}');
if isempty(iCBstop)
iCBstop = 0;
end
iBS = findstr(cMSG,'\');
if isempty(iBS)
iBS(2) = length(cMSG)+1;
end

Jonathan, an updated version is on its way, the bug is fixed, I changed the behaviour to also list FeX contributions not found locally so that those can be downloaded. In addition to that I modified the function to also take an optinal function handle as input argument, that will be used to produce the list of functions to watch for. That way users get the flexibility to create that watch-list whichever way.

Andrii, just out of curiosity, what would you want to get from: https://maps.google.co.uk/maps?q=guggenheim+museum+bilbao&hl=en&ll=43.268728,-2.933803&spn=0.001457,0.002902&sll=43.267445,-2.937035&sspn=0.002914,0.005804&t=h&hq=guggenheim+museum+bilbao&z=19

31 Jan 2012 UIMAGE - UIMAGESC Display image with non-linearly spaced axis. Author: Frederic Moisy

Just a question: What improved features does this provide compared to simply calling:

pcolor(x,y,c),shading flat,axis ij

Works and follows a gap in Mathworks contour functions. Much apreciated!

There is a fundamental flaw in CheckVersion. The current .m file's date is checked against the (Updated ...). The problem is that, unless the uploader and TMW publish the file on the same day it was last changed, this tool will signal false positives. I would suggest asking TMW to provide a "last modified" field, next to each file entry to make this design flawless.

I love the idea of this, but unfortunately there's a few problems. The variable iAvailable starts at 1 so it will always try to build the table for you even if no updates are available. Which causes an error... Set iAvailable to zero and increment it first thing within the if statement. It would also be good if we could just give it a list of FeX IDs and if the file is not found give us the option to download and install it. I'll give you a chance to work this further before I give you a rating.

19 Jun 2013 Scrollsubplot scrollsubplot(n,m,p) p<0 and p>nm, Extends subplot to infinite canvas ... Author: Bjorn Gustavsson Jakob

Hi,

nice tool, could you make it working with asymmetrical subplots like for example scrollsubplot(2,2,[1 3])?

Would be cool
