Calculate percentage difference between two variables

I want to calculate percentage difference between measured and calculated variables along the time axis. Both measured and preducted variables are arrays of different size. I want to calculate the percentage error for the corresponding time.

[Torsten]

percentage_error = abs(1-predicted/measured) * 100 ?

[Adam]

Or

100 * ( predicted - measured ) / measured

?

Thank you for your answer. Yes, this is what I want but it will not work as size of the array predicted is different from size of array measured. And hence predicted(xx) is not at the same time as measured(xx).

You should resample one array's elements according to other array's time.

Check the below function for this:

resample

After resampling your 2 arrays will be the same size. You can substract.
