My system hangs on executing the code. i am using vpasolve() to calculate m15 and using that m15 again to another equation to plot.

syms beta15
eqn15 =cot(def15)== tan(beta15)*(((k+1)*m*m)/(2*(m*m*sin(beta15)^2-1))-1);
s15 = vpasolve(eqn15,beta15,1);
S15=abs(s15);
n15=2+(k-1)*(m*sin(S15))^2;
d15=(2*k*(m*sin(S15))^2-(k-1))*(sin(S15-def15))^2;
m15=(n15/d15)^0.5;

hold on
A(4)=plot(-theta15-15,pr15,'color',[0.8500 0.3250 0.0980],'LineWidth',1.1);
hold on

This appears to be similar to the problem presented in Solving for angle (Beta) using vpasolve although here several variables are either missing or undeclared.
