Question

I have the data sets MI and XLead and create a graph like this: plot(Xlead,MI)

That graph has a peak – I can find the MI value at the peak like this: maxMI = max(MI);, but how do I find the Xlead value for when MI is max?

Answer 1

The max function returns an array of two objects:

[C,I] = max(...)

C – is the max value, I are the indices of the max value

So if you do:

[maxMi, ind] = max(MI);
maxX = Xlead(ind)

then you should get the value of X for the max MI in the maxX
