Numerical Optimization: Write a numerical objective function
显示 更早的评论
I have to minimize a numerical objective function of the form:
min Σ(x(i+1)-x(i))^2, i=1..10 and x(i) are the variables to be optimized
I tried using the symssum but doesn't give any results and I have not found anything else in the documentation. Does anyone have any idea how to write this? Thanks in advance.

@(x) sum(diff(x).^2)

It would only return the derivative if you are passing a symbolic variable to it; you should be passing a numeric vector to it.
For extra certainty you could code
@(x) sum( (x(2:end) - x(1:end-1)).^2 )
