Arrayfun with Extra Parameters

I have a function myfunc(x,y,L,P) designed to take x,y coordinates and additional parameters L(11x2 double) and P(36x1 double). When I test the function, it works properly. When I try to repeat the calculation using a vector of coordinates, arrayfun and an anonymous function, it fails. Hopefully the code snippet below is enough for someone to help me diagnose.

x = 10;
y = 1;
Test1 = myfunc(x,y,L,P); % Works!

f = @(x,y)myfunc(x,y,L,P)
Test2 = f(x,y) % Works - matches above!

a = ones(5,1)*x;
b = ones(5,1)*y;
Test3 = arrayfun(@f,a,b) % Unrecognized function or variable 'f'

Answer 1

Test3 = arrayfun(f,a,b)

instead of

Test3 = arrayfun(@f,a,b)

Well that was easy. Thank you!
