Hallo,

I generated a .csv-file engauge digitizer like this

x,D
100.1,200.3
101.3,200.4
...

Then I'm going to load and plot it:

clear
Array=csvRead('C:\Users\Karl\Desktop\SCILAB\D_Werte.csv');
col1 = Array(:, 1);
col2 = Array(:, 2);
plot(col1, col2)

function y=poly2dfit.sci

Q:
How can I do a polynom fit and derivate the fit?
