06 Mar 2015 SCP/SFTP from Matlab This package enhances Adam Leadbetter's "SSH from Matlab" package with SCP/SFTP functionality. Author: Kostas Katrinis Shanqing Cai

Please note that in order for this M function to work, the following Java classes need to be available on the MATLAB Java class path:

ch.ethz.ssh2.SFTPv3Client
ch.ethz.ssh2.Connection
ch.ethz.ssh2.Session
ch.ethz.ssh2.SFTPv3FileHandle

One option is to use Ganymed SSH-2 for Java, available at:
http://www.ganymed.ethz.ch/ssh2/

See the page below for instructions on adding Java class path in MATLAB:

Very nice work! However, Cochran's Review Manager can do it quickly and easily while minimizing errors on user's end. It can also quickly generate the funnel plot which is many a times a need along with the forest plot.

Thank for your rating, Mr. Mailfert.
But I could not find a problem that you mentioned.

I have tested it using this code.

=======================================
clear all;
u16 = uint16(rand(10, 10)*255);
rgb = uint8(rand(10, 10, 3)*255);

saveastiff(u16, 'test.tif');
options.append = true;
options.color = true;
saveastiff(rgb, 'test.tif', options);

tif = loadtiff('test.tif');
if (all(all(tif{1} == u16)) && all(all(all(tif{2} == rgb))))
disp('no problem');
else
disp('error');
end
=======================================

Could you tell me a little more about your problem?

05 Mar 2015 Search( filetype,folderpath) Recursively searh folder path Author: anthony bobbie Jan Simon

Jan Simon (view profile)

The message 'file type cannot be empty' does not match the test "exist(folderpath, 'dir')==7".

There is a problem with the indexing: The last element of the output is empty. Why does the FOR loop end at "file_count-1" and not "file_count"? You need the 1-based indices in the Matlab cell, but a 0-based index for the .NET array:
for x = 1:file_count
output_args{x}= char(arfi.GetValue(x-1).FullName);
end

There is no need to limit the file specifier to start with '*.' .

Wow. This is seriously bad, convoluted code, to do what can be done in one short line.

2*(dec2bin(0:15) - '0')'-1

As Stephen points out, no help. Essentially no comments. No clue. I had to laugh at one of the very few comments in the entire code...

%while (count<=j-1)

Yep. Not a comment at all, just some deadwood from when the author was writing the code.

Thank you for this function. How can I do the same thing if the shaded variable is the x and not y? (plot of altitude vs concentration for example, where the concentration has a range of values to be calculated with the shadederrorbar function)

No help, no comments, no explanation, no examples, no description, no clue as to what this code actually does.

Poor MATLAB code: multiple loops with if and break statements, which is just calling out to be vectorized:

Nike Dattani

I've been using EXPAND for a number of years, and it's part of my open source software FeynDyn for numerically calculating Feynman integrals.

Regarding Yair Altman's comment below:
Have the speed and memory of EXPAND been retested now?

I'm wondering if I should scrap EXPAND from my software.

Also, MATLAB has it's own EXPAND in the Symbolic Toolbox for expanding expressions like (x+y)^2.

Thanks for the input.

Very useful. Thank you.

I would like to change the color scale of the 3D plot, which normally uses the max,min values of the plotted dataset. I managed to change the range of values in the colorbar by modifying the function "isocontrols.m", however it does not seem to apply to the 3D plot it self.
Thanks in advance for your help and suggestions.

Sébastien MAILFERT

Hello,

this is really interesting and I'm currently using it for my application.
I have a problem to mix in one multiple frame different images.
I'm able to append in one file multiple images in uint16 format or multiple images in RGB.
I have to mix both types. How could I do?
Thanks for your help.
I used different options like append, color, etc. but when I append uint16 and RGB data, the file is not correct.
Thanks for your help.

05 Mar 2015 Full Vectorization of Solar Azimuth and Elevation Estimation sun_postion by Vicent Roy vectorization in both time and location Author: Charles Rino John Wood

OK. The gross error in the zenith calculation is in line 7 of sun_topocentric_zenith_angle_calculateR. You are only using the first latitude value. This should read:
% Topocentric elevation, without atmospheric refraction
argument = (sin(loc_llh(1,:)* pi/180).*sin(topocentric_sun_position.declination * pi/180)) + ...
(cos(loc_llh(1,:)* pi/180).*cos(topocentric_sun_position.declination * pi/180).*cos(topocentric_local_hour * pi/180));
true_elevation = asin(argument) * 180/pi;

I haven't followed through the fine scale discrepancies, but I suspect they are due to errors in the Vincent Roy transcription of the Reda & Andreas algorithms that haven't been corrected yet.

Dear Mayank

As the title of this post suggests, it is a "feature selection" technique not really "feature extraction". Feature extraction includes feature construction and maybe selection. In this post only feature selection is done, i.e., assuming that you already extracted the features of interest.
