Answer by István Zachar for How to find all the local minima/maxima in a range
Just for the record, if you are willing to (re)sample your function to have {x, y} pairs instead of a regular function or InterpolatingFunction, there are multiple methods available (see for example...

Answer by azdahak for How to find all the local minima/maxima in a range
Since you're fitting your data with a cubic spline, and defining $f(x)$ as the derivative of the interpolation function, then if we solve for $f'(x)=0$ for the critical points, the resulting function...

This can be done using event location within NDSolve. I start off as below (note f is slightly modified from what you have, mostly to rescale it).GetRLine3[MMStdata_, IO_: 1][x_: x] :=...
