function [call_value]=different_k(S, r, sigma, t, steps)
call_value=zeros(226,1);
for i=75:300
call_value(i-74,1) =european_call_binomial(S, i, r, sigma, t, steps);
%plot(call_value(i-74,1),i);
end
x=75:1:300;
y=call_value(1:1,1);
plot(x,y)
I 'm trying to assign the value to call_value. However, the result says call_value has not been defined. Did I made a in call_value(i-74,1)? how should I fix this ?
