12 May 2011 Write Cell Array to Text File A cell array is written to a delimited output file, incl. options for appending & custom delimiters. Author: Roland Pfister

Its OK. I had a problem...could be a Mac thing. Instead of making a new line in the file, the text appeared in the file as "Hello\n", that is the special characters appeared in the file.
To get around the problem I changed the program to read:
fprintf(fid,'%s\n',astring)
That is, I put the special character directly in the second parameter. Then it created a new line.

02 Jun 2010 Historical Stock Data downloader Used to retrieve historical stock data for a user-specified date range Author: Josiah Renfree

Can it be set for higher frequency data? Maybe every hour or every fifteen minutes? Good program !

27 Apr 2010 maze_solution Solves mazes using mathematical morphology - find the route through the maze. Author: Image Analyst

Brilliant !!!

11 Feb 2010 trig functions in degrees The six standard trig functions modified to take arguments in degrees. Author: Jared Stofflett

Yes it is helpful. But as Duane notes, the sind function in Matlab does the same thing now.

18 Dec 2009 Why use fftshift(fft(fftshift(x))) in Matlab instead of fft(x)? Explain why we use fftshift(fft(fftshift(x))) in Matlab instead of fft(x) Author: Kan Wu

Very interesting!

Good idea to port this to a .m file. Thanks for doing it!

04 Nov 2009 rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman Jan Simon

Some indices are confused: Dim=2 and 3, NumRot=1 and 3. I've used your correct working first submission for checking the results. I'll try to contact you by email.

27 Oct 2009 rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman Matt Fetterman

Hi Jan, Thanks for comments. I did update it. It is hard to write it using the permute command but hopefully got it right !

26 Oct 2009 rot90 in 3D This function extends the rot90 command to 3D. Author: Matt Fetterman Jan Simon

Sorry - I forgot some indices:
Y = ROT90_3D(X,1,1) equals:
M = PERMUTE(X, [1,3,2]); Y = M(:, size(X,3):-1:1, :);
Other equivalents:
ROT90_3D(X, 1, 2):
Y = X(:, size(X, 2):-1:1, size(X, 3):-1:1);
ROT90_3D(X, 1, 3):
Y = PERMUTE(X(:, size(X,2):-1:1, :), [1,3,2]);

For the other dimensions, this formulas are cyclical shifted. For e.g. [100 x 100 x 100] arrays this takes about 2% of the time of ROT90_3D, so I'd suggest to update the submission.
