Find the partial minimums in a set of values

Hi everyone! I have the graphics i show you in the image and i would like to know the distance betwen the two minimum point in the middle of the graph. I mean betwen around 30 and 60. How could i find this points? I have thought I could aproximate to a polynomial function and find the minimums...

• Use findpeaks(-data)
• Choose peaks that lie in 23 < x < 27 and 58 < x < 62

Nice! Thank you!!

I'd probably use islocalmin instead of findpeaks on the negative of the data.

much better, thanks Steven! Although I solved it using -data...
