How to rectify this error,

Not enough input arguments.

Error in computeCost (line 3)

m = size(age,1);

the code is given below

function [J,grad] = computeCost(Theta,age,chol)
m = size(age,1);
age = [ones(m,1) age];
h = sigmoid(age * Theta);
J= -(1/m)*sum(y .* log(h) + (1-chol) .* log(1-h));
grad = zeros(size(Theta,1) ,1);
for i=1:size(grad),
    grad(i)=(1/m)*sum( (h-chol)' * age(:,i));

end

Don't run the function usinf run/ F5. Give inputs and call it.

Theta = pi ; 
age = 30. ; 
chol = rand ; 
[J,grad] = computeCost(Theta,age,chol) ;

okay...Thank you so much.
