as I already noticed in this community, I am not alone with that problem. I have tried several solutions proposed in here but it didnt help for reasons like: Old Matlab Versions (interp1 has changed significatly) or another kind of problem.
Let me first tell you what i am doing to make it easier for you to help me:
I a for-loop with approx. 30.000 iterations i use interp1 several time (5 times per iteration - see the profiler below).
Example of the call: [interp1( x, y, xq)]
Here, x is a vector (length 10.000) and y is also a vector (length 10.000) and xq is a vector (length 50.000 or more).
The problem is also that y changes in each iteration and therefore, I cannot precompute any operation (xq is also updated each iteration).
I would be very grateful if you had any suggestions to improve the computational time in this case.
Best regards, Ilya
