Problem using interp1 with a sharp change in the data
조회 수: 8(최근 30일)
I have a vector of data and I want to interpolate it using interp1. The problem is that there is a sharp increase in the values of the vector and the resulting graph does not reproduce the data propperly.
Is there a way to make the interpolated data reproduce the sharp jump propperly?
I will attach a figure where my issue is displayed.
Any answer is appreciated.
Thank you very much.

Try using ischange to detect these sharp changes in your data and interpolating using only data in the same "piece" of your curve (where pieces are delimited by the ends of your data sets and the change points) as the points for which you want the interpolated value.
