Hello, I have this graph and I want to find out when does the slope changes from negative to positive around index ~100, for each group (younger and older), using polyfit.
Each line in the plot is a matrix column (ignore the shaded area, that's the standard error of the mean).

The ischange function (introduced in R2017b) is helpful here.
