How can I solve this easy equation with fsolve? (beginner)

Error in ==> fsolve at 11
K= fsolve(@(K) ((a*gamma)/rk)^(1/-0.57),start)

Code:

clear all
close all
clc 

rk=0.1641;
a=3.71;
gamma=0.43;
start=0.1;
K= fsolve(@(K) ((a*gamma)/rk)^(1/-0.57),start)

The only problem I see is that the function you are solving is not a function of ‘K’.
