Flexible/sporadic pausing within a loop
Background: I work in a lab that uses the playrec MEX file to access the soundcard via an ASIO driver. This lab uses playrec to present stimuli (audio signals) and record responses (audio signals) from human ears. We've written a function that calls playrec within a loop ("stimulus loop") that is incremented until th... 20 Jul 2010 11:20

Error message for rayleighchan
Hi all; I've been using my own Rayleigh fading simulator for a long time. Thought I would give rayleighchan a try; looks simple enough. However I'm getting this error message when I try this in the command window. The command is copied from MATLAB's help example. Any help would be appreciated. I'm using version R2008b.... 19 Jul 2010 23:27

how to generate random variable with constraint?
I need to generate 5 random variables between [0,1], let's say a, b, c, d, e. The constraint is that a<b<c<d<e. How to make this happen? Please advise. thanks ... 22 Jul 2010 15:48

Speed bottleneck
Hi all, I'm building a simulation model of epidemics. I'm struggling with speed issues on some of my functions. I've gone through a fair amount of vectorization and such but remain well under the speed I'd like to achieve. I would appreciate any tip or trick to make this run faster. I've highlighted the lines that tak... 20 Jul 2010 04:50

plotting 3d 'cone'
We'll I've got a bunch of data sets with lateral g, longitundinal g, and the speed at which they were taken at as values. The lat g and long g basically make it a friction circle, but I need to plot that data in relation to speed. I'd like to plot it so it creates a cone like shape, then be able to look at slices of th... 20 Jul 2010 20:10

how do I find the common values among multiple arrays?
Should be a simple one though I've hit a brain block on how best to do it. I have multiple integer arrays and I want to find all the common values between these arrays. Kind of an anti-unique() function. Any help or ideas? ... 30 Jul 2010 11:52

publish function
What functions write Latex codes when we call the publish function?? I need to modify it little bit so that when matlab generates a latex code, I always want it to write \subsection{....} \includegraphics instead of just \includegraphics I am looking at the "publish" function, but I haven't been able t... 19 Jul 2010 21:16

empty histogram
I use hist3(m_by_2_matrix) to make a histogram. I'm making a movie of the way the histogram changes over time. At certain times, m_by_2_matrix is empty. Is it possible to create a histogram with empty data? hist3([0 0]) makes a single spike at 0. I'd like a flat histogram of all 0s to fill the plot at this time step ... 19 Jul 2010 22:22

Easy Bioinformatics Question
Hi All, I'm new to bioinformatics with MATLAB, and my web and documentation searches have thus far not helps, but I apologize for potentially not knowing what to search for. Anyway, I'm analyzing the primary amino acid sequences of ~500 proteins, and I'd like to be able to work with some of the data generated by ... 20 Jul 2010 20:10
