mean of a random signal during simulation(realtime) with simulink
Halo there, Could you please help me in finding the mean of a random signal(ex. noise or an unsteady current signal)during simulation. i.e, in realtime. please let me know with the blocks that can be of help. I cannot use the matlab functions because the dspace real time interface cannot compile them.so i need to... 6 May 2008 22:22

How can I find intervals?
Hi I have a signal and I want to identify intervals in which the signal shows a specific characteristic (that I can define, e.g. intervals in which the signal is <1). How can I find such intervals? I want to know the length of each interval, and how many there are. Is there anyone who can explain me how to d... 6 May 2008 22:22

Sparse matrix product again

The reason I say that is because a mexFunction could do Atr(:,rows_j)'*B(:j) without forming the Atr(:,rows_j) matrix as an intermediate step. Wow, that really speeds it up. Thanks! :-) Again, I did some... 7 May 2008 11:47
