%Las ecuaciones

% 1.- CARBON solves for Xch4
s1 = ((Yc*F)/MWc)*(22.4/G)-Xco-Xco2-Xch4;

% 2.- HIDRÓGENO solves for h20
s2 = ((22.4/G)*((F*Yh)/MWh)+(2/MWh20)*(W+S)-2*Xh2-4*Xch4)*0.5-Xh2o;

% 3.- OXÍGENO solves for co
s3 = ((Yo*F)/MWo)+(W+S/MWh20)+((0.23*A)/MWo2)*2*(22.4/G)-2*Xco2-Xh2-Xco;

% 4.- NITRÓGENO solves for F
s4 = ((G/22.4)*(2*Xn2)-(2*(0.77*A)/MWn2)*(MWn/Yn))-F;

% 5.- fracciones másicas de compuestos, solves for N2
s5 = 1-Xco-Xco2-Xh2-Xch4-Xh2o-Xn2;

% 6.- constante Kpw, solves for h2
s6 = ((Xh2o*Kpw)/(Xco*P))-Xh2;

% 7.- constante Kpb, solves for co2
s7 = ((Xco^2*P)/Kpb)-Xco2;

% 8.- agua
s8 = (F *(H/(1-H)))-W;

% 9.- steam

%Vector solución 

sg = [s1; s2; s3; s4; s5; s6; s7; s8; s9; s10];

This is my code: 10 unknows and 10 equations.

And then in another file i have a script that calls for fsolve

% syngas script

% initial guess

F0 = 1;
Xco0 = 0.0001; Xco20 = 0.0001; Xh20 = 0.0001;
Xch40 = 0.0001; Xh2o0 = 0.0001; Xn20 = 0.0001;
W0 = 1; S0 = 1; A0 = 1;

% pack up initial guess
X0 = [F0; Xco0; Xco20; Xh20; Xch40; Xh2o0; Xn20; W0; S0; A0]; 

% call fsolve
%
fhandle = @syngas;
X = fsolve(fhandle,X0);

% Display answers
%
disp('F0, Xco, Xco2')
disp(X(1:3))

disp('Xh2, Xch4, Xh2o,Xn2')
disp(X(4:7))

disp('W,S,A')
disp(X(8:10))

And this is the error i get:

>> syngas
Not enough input arguments.

Error in syngas (line 6)
F = X(1);
 
>> 

i'm not sure what it means. Any advice? thank you!!

Do not give the name of the function at the command line, give the name of the script.

that was the problem. Thanks!

Name of the script should be different than that of the function.

[p.txt]

Jesus Christ, that was it lol

thank you!
