I have a system with 11 equations and 9 unknowns, how can I solve these equation sets?
For example
ct=teta0+c*d+teta1p*a
gama0= teta0*a*b*c*(teta1p+d);
gama1s=(a*gama0+b)/c;
gama1c=teta0+0.75*teta1p+c*d;
wy=e*cos(tetaf)+cos(fi)......+sin(tetafp);
Wi=g*cos(tetaf)+...+cos(tetafp);
... and There are 5 more equations with tetaf, tatafi and tetafp unknowns.
known parameters:a,b,c,d,e,f and....
uknown parameters: teta0,teta1c,teta1p,gama0,gama1c,gama1s,tetaf,tetfp,fi

See fsolve(), or if you want to put upper/lower bounds on the unknowns then see lsqnonlin().
