Dear all,
Do I understand correctly that the function intrlv ( http://www.mathworks.de/de/help/comm/ref/intrlv.html) is supported only in Matlab2012b, but not in 2012a?
Is there an easy way to substitute this function with something that will work in 2012a?
I am using a university licence so the solution - update the Matlab will not be of help. But now I see on the internet people asking questions about this function back in 2009.. And on my computer I get the message Undefined function 'intrlv' for input arguments of type 'double', and also no description or anything about intrlv in the Help.
I am trying to use a code for Compressed Sensing and it has this function everywhere. Also a simple example like
p = randperm(10);
a = intrlv(10:10:100, p)
gives me the same error.
Thanks!

That is not accurate. intrlv.m is part of R2012a. Perhaps the issue is that you do not have the Communication System Toolbox in your installation.
Enter

at the command prompt to see what you have installed.

It is true, I don't have the Communication System Toolbox. Thanks!
