Hi,

I´m trying to solve following system of equations in matlab:

p3=lambda*sigma^3*(s^3+3*delta^2*s)
p4=lambda*sigma^4*(3*delta^4+6*s^2*delta^2+s^4)
p5=lambda*sigma^5*(15*delta^4*s+10*s^3*delta^2+30*delta^2*s+10*s^3+s^5)

sigma,p3,p4 and p5 are known and i need to determine lambda,delta and s.
I' ve tried functions solve and fsolve but it didn't help.
Can anyone help me please?
Thank' s in advance.
