I have numerical values assigned to several parameter.
Using these parameters, I want solve fsolve such as below.
But it keeps giving error messages saying that the parameters are
not defined. Should I write every numbers instead of characters in
the function? Help me, please!
g=0.03;
b=0.45;
a=0.3;
aa=2.5222;
rho=0.5;
r=1+rho*b/(1+a*b);
th1=0.000045;
th2=0.000037;
R=900;
S=210;
B=1/(1-a-g);
A12=1.5;
A11=1.2;
A02=1.9;
A01=1.8;
F = @(E)[2.52*( g/E(2) - r*(th1+W*th2) ) - g/E(1) + (th1+W*th2);
2.52*( g/E(4) - r*(W*th1+th2) ) - g/E(3) + (W*th1+th2);
R - ( E(1)+E(2)+E(3)+E(4) );
((exp( -th2*( rho*S +E(2) + E(4) ) ))/(exp( -th1*( rho*S +E(2) + E(4) ) ))*A02/A01)^(B)-E(4)/E(2);
((exp( -th2*( rho*( rho*S +E(2) + E(4) ) +E(1) + E(3) ) ))/(exp( -th1*( rho*( rho*( rho*S +E(2) + E(4) ) +E(1) + E(3) ) )))*A12/A11)^(B)-E(1)/E(3);
W-E(4)/E(2);
E(4)/E(2)-E(3)/E(1)];
E0=[300];
options=optimset('Display','iter');
E=fsolve(@planerenergy, E0, options)
ps. I also tried to make the function as seperate function such as
xx.m file. But it still gives the same error message such as
??? Undefined function or variable 'g'.
