Comments and Ratings

Does the job and has been well coded since previous (now redundant) negative comment was submitted.

Needs some TLC and polish; though a good utility function.

Unfortunately this function errors for non-numeric input.

Ohh.. Now I could understand, why I did not get roundn function. I didn't install Mapping tool box in R2007b. ThxJohn Greeb for the info.

cool. this is one of the best files i have ever found.

Wow, this is a labour of love and is nearly magical for me. For months I have been struggling with the infuriating difficulty of exporting small figures with LaTeX-rendered xlabels.
The automatic mode of your code improves the situation for me. I need to use the detailed version to get it right, and that means fiddling around by hand for each plot. Being reduced to that again is of course, a great shame and a significant failure for Matlab, but at least I know how now. To Mukhtar (and the blog which inspired him) -- THANK YOU!!!

This seems very useful. I am surprised that MATLAB doesn't have a built-in function to to rounding-off up to a desired number of decimal places.

I stick with saveascii.m

By the way, why did I rate this submission as only a 4? After all, it seems to work reasonably nicely.

I did so because I had to figure out that it does not work if I wanted to append a line with numeric data, that I had first to convert the numeric data to a string. While this is not incredibly hard to do, I had to figure that out by testing the code. There is no statement in the help that this will not work. Since the help is really only an example of use, it gives you only a hint of what DOES work. You need to infer the rest.

Excellent help would have told me all I needed to know about how to use it, without ever testing the code.

Thank you. Great addition for me. :)

I forgot to mention two things about this post.
If you have the FIXPSLINESTYLE http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=17928&objectType=file
in your working directory, then PRINTFIG will apply that to the eps output. If you have MiKTeX installed (and on your path), then the pdf output is generated from the pdf output by using epstopdf.
I would encourage users to download FIXPSLINESTYLE because it improves your output.

This file is no longer needed if you download SETAXES I recently submitted.

Function directionally derivative can be calcolated faster in the following way

syms a;
syms f1;
f1 = subs(f,x + a*X);
Xpdf = subs(diff ((f1-f),a),a,0)

i changed the code line after "S=..." to:

    B = S([ 1 1+find(diff(S)) ]);

and now it works for me, too. Without the change i got the message: ??? Error using ==> vertcat
CAT arguments dimensions are not consistent.

This is just what I've been looking for, thanks so much!

nchoosek is for scalars only.

I found a serious problem. Since updating is temporarily unavailable, please remove or comment out the following lines, until I update the file.

set(0, ...
    'defaulttextfontsize', 8, ...
    'defaulttextfontname', 'cmr', ...
    'defaultaxesfontsize', 8, ...
    'defaultaxesfontsize', 8, ...
    'defaultaxesfontname', 'cmr')

I have found a very serious problem. Since the update is temporarily unavailable, I am mentioning the correction here. Please change line 45 from
   set(ax, ...
to
   set(0, ...

Dear Carlos,
You seem to have completely missed what I meant. My dear, in my first syntax ISWHOLE(X), X is an array, which means it can be a vector or matrix. My second syntax ISWHOLE(X1,X2,..,XN) is for the general case when X1, X2 ,.. XN are arrays (vectors or matices). Matlab is an array oriented language, so I don't have to write that explicitely. Matlab users get it usually.

Neat.

Good but, why not vectorized? And why not make it for any kind of arrays? There's not need for varargin.

Check the inside of file Fibonacci.m by David Terr.

I was laughing out loud when I got the error mesage: ??? Undefined function or variable 'isfloat'. Only the most incompetent programmer would put in requirements of that type in a trivial function file like this.

Remedies a clear lack in matlab built-in functions. Very handy!
