I'm creating an application using App Designer which involves the use of syms to solve an implicit equation.

Unfortunatelly in Standalone or Web applications created with Compiler syms can't be used. Do you know an alternative to solve the following equation without using the symbolic math toolbox? Or any other solution to bypass this problem?

syms R 
g = ((1+nu)*(1-2*nu)*(1-1/(R/b0)^2))/((alpha-1)-(1-2*nu)*(1+alpha)/(R/b0)^2);
omega = -(2*(1-2*nu)*(1-nu^2))/(delta*(alpha-1))*((alpha+1/beta)-(nu/(1-nu))*(1+alpha/beta))/((alpha-1)-((1-2*nu)*(1+alpha)/(R/b0)^2))/(R/b0)^2;
S1 = 0;     
for n=0:1:10
    if n==gam
        S = k*omega^n/factorial(n)*log(R/a);
    else
        S = (omega^n/(factorial(n)*(n-gam))*((R/a)^(k*(n-gam))-1));
    end
    S1=S1+S;
end    
eqn = (nn/gam)*((1-g/delta)^((beta+1)/beta)-(a0/R)^((beta+1)/beta)) == S1;  
sol_R = vpasolve(eqn, R, [a0 Rpl_max]);
