Matlab goes into busy state when input is random and big.

On passing a random array of 8000 elements as input matlab goes into busy state..but my code works fine if the input is a simple sine wave array of 1000 elements..any help?

What are you passing the input to ?

There could be an infinite number of reasons. E.g. your code could contain a loop like this:

function Y=YourFcn(X)
while numel(X) > 1000
end

Without seeing the code, it is impossible to guess the reason for its behavior.

What happens if you pass in a random array of 1000 elements? Same performance as the sine wave?

Are you running out of RAM and going to use virtual memory? That will certainly slow processing, as well. Your system has a utility built in that will let you monitor this.

Hello Gautam

If you are using randn, this comes from a symmetric distribution. In that case generate 4000 and change the sing.

Hope it helps, best regards
