Hello everyone,
I want to analyse my Cyclic Voltammetry data on its peaks, which has increasing and decreasing X values and their own corresponding Y values. For this, I just installed the necessary toolbox, but when I try to run the following code:
[pks, LOCS] = findpeaks(GlucoseS3{:,4}, GlucoseS3{:,1});
I get the following error:
Error using findpeaks
Expected X to be strictly increasing.
I reckon that the code recognises GlucoseS3{:,1} to be X, and have increasing as well as decreasing values.
How can I change this code to accept decreasing X values, as I have to analyse a lot of datasets with each 700 points.

May be you should try:
[pks, LOCS] = findpeaks(GlucoseS3{:,1}, GlucoseS3{:,4});

Unfortunately it doesn't work, but I've found another way by using gradient and find(x<0.001). Still, thanks for your answer!
