I keep getting the error message "Undefined function or variable 'z'." when I run:
z = [0.388039 0.264102 0.185497 4.66E-02 2.58E-02 7.68E-03]; %Smoke 1
D = 10; %mg
V = 25;t = [1.0 3.0 5.0 14.0 18.0 24.0];k1 = [0 1];[kv,kval]=fmin(k1,D,t,z);
which calls the function below:
function [kv,kval]=fmin(k1,D,t,z)[kv,kval]=fminsearch(@fminfunc,k1); function f = fminfunc(kv) sum=0; for j=1:6 sum = sum + z(j) - (D/kv(2))*exp(-kv(1)*t(j)); end f = sum^2; return return
and I get this output:
Undefined function or variable 'z'.Error in hw4c_1>fminfunc (line 22) sum = sum + z(j) - (D/kv(2))*exp(-kv(1)*t(j));
I'm not sure why the variable is undefined when I've already passed in the variables to the function. Please help
