Suppose, for each alpha, I have to find a delta which is the highest positive root of the equation A^2-4*B*beta=0. The expression of A, B are given in terms of alpha and delta. How to get that and how to plot alpha vs delta plot.
beta=0.85;gamma=.15;theta=0.1; alpha=.303:.001:5 syms delta A=-alpha*beta + alpha.*delta + gamma*beta + beta; B=alpha.*theta*(beta -delta) + gamma*beta; rr=solve(A^2-4*B*beta == 0) plot(alpha,rr)
