This is the nozzle expansion ratio equation and I am attempting to solve for the exit pressure. It is quite complex to rearrange for Pe (exit pressure) by hand so I figured I would put it into Matlab and solve symbollically. I keep getting an empty vector for solveEqn… I’m quite inexperienced with solving symbollically in Matlab so I would appreciate some help. Thank you.

syms Pe k A_ratio Pc

A_ratio = 2.06265092035577;
k = 1.1876;
Pc = 3447378.65;

eqn = ((k+1)/2)^(1/(k+1))*(Pe/Pc)^1/k*sqrt((k+1)/(k-1))*(1-(Pe/Pc)^(k-1)/k) == A_ratio;
solveEqn = solve(A_ratio, Pe);This is the nozzle expansion ratio equation and I am attempting to solve for the exit pressure.
