I just need a quick clarification on how to read this function

f(x) = sigma of X^2, starting at j=1, and n

so does that mean that f(3) would equal to 36, if n=4?

I forgot to mention that this is a DeJong Equation, and I need to implement in the matlab

Are you sure this is the function:

[tex]f(x)=\sum^{n}_{j=1}x^{2}[/tex]

The term is independing of the sum, so the function is just:

[tex]f(x)=nx^{2}[/tex]
