MATLAB: To find value of unknown variable

Question

syms a1 K n E q

eqn = (a1/K)^(1/n) + (a1/E) == q;

E=30000;

K=174.6;

n=0.202;

q=0.02;

solx = solve(eqn, a1)

I want to find value of (a1) but with this code I cant find it. suggest me correct solution

Answer 1

You are trying to solve the equation symbolically and it takes a long time/fails.

If you are okay with a numeric solution change the last line to:

solx = vpasolve(subs(eqn), a1)

>>

solx =
