how to calculate the local slope degree of this curve in its point having the x and y values of the curve:
I tried to do it with the following :
slope = diff(y) ./ diff(x);
or :
slopeY = (y(2:end) + y(1:end-1))/2;
but my results doesnt seem to be correct. Thank you.

In what way do the results not seem correct? Do you have manually calculated results that differ?

I would use gradient rather than diff, since the output vector is the same length as the input vector.
