Hi Søren
Thanks for your response. trapz is a function (trapezoidal rule for simple
integration), whilst t and p are vectors that hold the time and pressure
respectively. As I am (re)learning this style of language your term vectorize
will help, and I will do some searching for methods on how to achieve this. I
did leave this this afternoon and finalised another chapter, so I am happy to
get back to 'the fun bits!',
Cheers
Rob

Hi,
So, you want to vectorize the following code:

> mx = limits(i,2); % get the max limit index
> imp(i,1) = [trapz(t(m:mx),p(m:mx))];
> end
Is 'trapz' a matrix or a function in the above code? If it is a matrix
then I don't think you can vectorize the code. Also is 't' and 'p'
functions or matrices? The way your code looks, I can't think of a good
vectorization, sorry :-(
But if n is approx 10, then I don't really think solving this problem is
worth your time. Since I'm answering this question to get away from
writing my thesis I can understand that solving such problems are more
fun then writing a thesis, but I think you should move on (I know I'll
stop writing this mail, and get back to my thesis ;-) )
Søren
