I'm writing a MATLAB function mfile which has input argument of some Nby1 vector.
Say this vector is [1,2,3]. I want to create a function handle representing a sum of x taken to the power of each number that appears in the vector, so in this case it is: f = @(x) [x^1 + x^2 + x^3]; (x scalar) The point is, I don't know how to define f when I don't explicitly know what the input vector is. Can anyone help me generate a general function handle? The trick is because N is variable.

v=[1,2,3]
f = @(x) sum(x.^v)
