Hi everyone,
I'm trying to minimiza and area. In my problem I have an exerimental curve and a polynomial and i want to minimiza the area between the two.
I have tried with this code but it does not work very well:
x=( Cp5_diff(m(1):c(1))-polyval(z,T10(m(1):c(1))) );
Area2=@(z) sum( ( x.*dt(m(1):c(1)) ) );
Do you have any suggestion?
Thank you!

Your objective function Area2 is written to be a function of z, but nothing in
sum( ( x.*dt(m(1):c(1)) ) )
depnds on z. Perhaps this is what you intended,
x= @(z) ( Cp5_diff(m(1):c(1))-polyval(z,T10(m(1):c(1))) );
Area2=@(z) sum( ( x(z).*dt(m(1):c(1)) ) );
