The following coordinates are given:
y=[96.9;67.6;36.1;120.2;40.3;51.7;71.0]
x=[216.6;318.33;418.3;535;636.66;753.3;856.66]
A third order polynomial compensation curve is now to be laid through these points.
It would be important here that the coefficients (p1 to p4) are stored in separate variables.
How exactly could I do that?

myfit=fit(x,y,'poly3');
From there you can extract the coefficients as myfit.p1, myfit.p2 etc.
