I would like to use the functions *derivative* or *numdiff* to numerically
differentiate a tabulated data such as

x = [0 2 5 20 40 60 80]';//time in minutes
y = [0.0956820 0.0480457 0.0277857 0.0036214 0.0002543 0.0002543
0.0001265]';//values of y

May I know the best way to determine dy/dx for the data set.

Thank you very much and God bless you
