How can I pass a function into a function and find the minimum?

Hi! I have a problem when trying to minimize a function with fminsearch. I have this function:
function [f] = myfunc(X)
x1 = X(1);
x2 = X(2);
f = 2*x1^2 + 2*x1*x2 + 2*x2^2 - 6*x1;
end
and I want to minimize the f(X+a*grad) where X and grad are known.
I tried this:
[f] = myfunc(@(a) X + a * grad);
a = fminsearch(f,0)
but it doesn't seem to work.
Do you have any suggestions on how to make my code work?

Please describe what you want to do.
the ‘f’ assignment and your fminsearch call make no sense.

solution:
f=@(a) myfunc(X + a * grad);
a = fminsearch(f,0)
