Hi all, I'm still farily inexperienced with matlab. I am trying to break up an equation into smaller parts (the 4 functions) to make it easier to check/modify when I integrate the Gammasigma function but I keep getting 'not enough input arguments,' and the error lists every function as part of the error. I know that I am doing something wrong with the variable calls but I am not sure what specifically my issue is or how to fix it.
syms Egam
ECrit = 5;sigmaT = 1; me = 510;
compton1 = vpaintegral(Gammasigma,Egam,15,30);
compton2 = vpaintegral(Gammasigma,Egam,11,30);
compton = compton1/compton2;
function Gs = Gammasigma(Egam,ECrit,sigmaT,me)
Gs = (exp(-exp(-((log(Egam)+1.2)./(.8)))-((log(Egam)+1.2)./(.8))+1)).*s3;
end
function sigma3 = s3(Egam,ECrit,sigmaT,me)
sigma3 = s2+(3.*sigmaT)./(8).*(1)./(((Egam)./(me)).^3).*(1-((Egam)./(me))-(1+2.*((Egam)./(me)))./(1+((Egam)./(me)) ...
.*(1-(1-(me)./(Egam).*((ECrit)./(Egam))./(1-(ECrit)./(Egam)))))-((Egam)./(me)).*(1-(me)./(Egam).*((ECrit)./(Egam))./(1-(ECrit)./(Egam))));
end
function sigma2 = s2(Egam,ECrit,sigmaT,me)
sigma2 = s1+(3.*sigmaT)./(8).*(1)./(2.*((Egam)./(me))).*((1)./(1+((Egam)./(me)).*(1-(1-(me)./(Egam).*((ECrit)./(Egam)) ...
./(1-(ECrit)./(Egam))))).^2-(1)./(1+2.*((Egam)./(me))).^2);
end
function sigma1 = s1(Egam,ECrit,sigmaT,me)
sigma1 = (3.*sigmaT)./(8).*((((Egam)./(me)).^2-2.*((Egam)./(me))-2)./(((Egam)./(me)).^3).*log((1+2.*((Egam)./(me))) ...
./(1+((Egam)./(me)).*(1-(1-(me)./(Egam).*((ECrit)./(Egam))./(1-(ECrit)./(Egam)))))));
end
Any help would be greatly appreciated!

Gs = (exp(-exp(-((log(Egam)+1.2)./(.8)))-((log(Egam)+1.2)./(.8))+1)).*s3;
That invokes the function s3 without passing any input arguments.
Remember that s3 might have been written
function sigma3 = s3(me_,sigmaT_,Egam_,ECrit_)
sigma3 = s2+(3.*sigmaT_)./(8).*(1)./(((Egam_)./(me_)).^3).*(1-((Egam_)./(me_))-(1+2.*((Egam_)./(me_)))./(1+((Egam_)./(me_)) ...
.*(1-(1-(me_)./(Egam_).*((ECrit_)./(Egam_))./(1-(ECrit_)./(Egam_)))))-((Egam_)./(me_)).*(1-(me_)./(Egam_).*((ECrit_)./(Egam_))./(1-(ECrit_)./(Egam_))));
end
MATLAB absolutely will not look at the calling sequence of the function to be called and match up the formal parameter names to find the closest name in the workspace and use that as the parameter. You must explicitly pass all parameters to a function being called.
