@irene,

How about a bar plot with bar.m?

Hi Doug, thanks for the explanation. I have a question related to your post. After getting the corresponding frequency of occurrence of y in each of the bins on the x-axis, I wanted to plot the data as a histogram plot. I want to come up with a histogram plot that looks like the ones on the following figure. I am not sure how to do it though. Any suggestion will be very helpful.

Hey Doug

Thanks so much for the video..made me finally understand how to bin in matlab. One question thought how would you bin x-y-z data?

Thanks again
Darlene

Ilya,

There are very often ways in MATLAB to accomplish tasks in fewer commands. It is mostly a matter of taste as to which to use.

I tend to go for things that are easily read and understood by the most people. I needed to look up the doc on ACCUMARRAY to understand the above code. So, I suspect many people, myself included, would take longer to understand the shorter code. It is all trade-offs, and knowing several ways of doing something is great.

Good find, I will have to add that to my bag of MATLAB tricks.

-Thanks,
Doug

The last loop could’ve been done simpler:

binMean = accumarray(whichBin, y, [], @mean)

I just checked out Stack Overflow last night, and it looks like a pretty cool community. I think I may start getting active over there.

Thanks for pointing it out!

3 years ago we built a community for French MATLAB users here:
http://www.developpez.net/forums/f148/environnements-developpement/matlab/
It is like the MATLAB Central except 5 of us can moderate the forum (check spelling, no SMS message, use of HTML markup to insert code or error messages…). It is currently divided in 4 parts : MATLAB , GUI, IMAGE and Signal Processing. For each part we promote the new releases of MATLAB and of course your blogs!
