matlab is taking too long to solve the equation.

while (FSt~=FSo)

FSo = FSt

Nu = W +(T.*sina)-(((p.*l.*sint) - (u.*l.*tanp.*sint))./FSo)

Nb = cost + (tanp.*sint)./FSo

N = Nu./Nb

up = sum((p*l*R)) + sum((N.*tanp*R)) - sum((u.*l*tanp*R))+sum(((FSo.*T*(R.*cosaw))))

down = sum(W.*xavg)

FSt = up/down %FOS after reinforcement%%

g=FSt-1

dp=diff(g,p);

p1=subs(dp,{p q r T},{C Gama Phi Tf});

p2=double(p1)

dq=diff(g,q);

q1=subs(dq,{p q r T},{C Gama Phi Tf});

q2=double(q1)

dr=diff(g,r);

r1=subs(dr,{p q r T},{C Gama Phi Tf});

r2=double(r1)

dT=diff(g,T);

T1=subs(dT,{p q r T},{C Gama Phi Tf});

T2=double(T1)

sums=double((p2*sig_tr_c)^2+(q2*sig_tr_gama)^2+(r2*sig_tr_phi)^2+(T2*sig_tr_T)^2)

c_prime= mu_tr_c-((p2*sig_tr_c)/sqrt(sums))*2*sig_tr_c;

gama_prime= mu_tr_gama-((q2*sig_tr_gama)/sqrt(sums))*2*sig_tr_gama; %here beta target =2

phi_prime = mu_tr_phi-((r2*sig_tr_phi)/sqrt(sums))*2*sig_tr_phi;

eq=subs(g,{p q r},{c_prime gama_prime phi_prime})

sol=vpasolve(eq==0,T)

end

end

For this I would like to suggest running ''Profiler'' on your code as workaround.

To know more about profiling refer below points:

• Profiling is a way to measure the time it takes to run your code and identify where MATLAB spends the most time.
• After you identify which functions are consuming the most time, you can evaluate them for possible performance improvements.
• You also can profile your code to determine which lines of code do not run.

You can refer this documentation link to see how to run profiler on your code-

You can also refer this link to look at some of the techniques that may help you improve performance-
