How to change negative values in anonymous function to zero and call it to next function?

Hello , I have a similar kind of problem like y = [1 2 1 1 1] and z = [1 2 -3 4 -5] and v(z) = z^3 now i have to calculate h(z) = v(z).*y but the condition is when i calculate h only negative values in the anonymous fn of v(z) must become zero. can someone tell me how?

z = [1 2 -3 4 -5];
y = [1 2 1 1 1];
v =@ (z)  z.^3;
h =  v(z).*y

I am getting h = [1 16 -27 64 -125] but i need h = [1 16 0 64 0]

v =@ (z)  z.^3 .*(z>=0);

v = @(z) max(0,v).^3;
