Matlab gets more and more slowly throughout program!

Matlab gets more and more slowly throughout program!

Matlab gets more and more slowly throughout program!

(OP)
I have a program that mainly consists of three interleaved for loops and and ode45 function in between them.
When I start the program everything works fine but it becomes more slowly with every loop.
I know that for loops are slow in Matlab but how can the program become more and more slowly?
All values that are saved for later use are written into a predefined matrix.
I have no idea where to look for the problem.
Thanks for any suggestions.

RE: Matlab gets more and more slowly throughout program!

Hi,

can you post some code?
Are you preallocating?

How many values?  How many are you adding?
