How to assign the value of a symbolic varible in a cell to other variable

i want to solve the equations for the variable M,

syms M; L = 5.0; A = 1.6; P = 0.0; w = 0.4195; R = 25; PBAR = P/(pi*w*R); e1 = A^3 - L*A^2.*(sqrt(M.^2-1) + M.^2.*acos(1./M)) - PBAR; e2 = L*A^2/2*(sqrt(M^2-1) + (M^2-2)*acos(1/M)) + ... 4*L^2*A/3*(sqrt(M^2-1)*acos(1/M)-M+1)-1; % evalin(symengine, 'numeric::solve(e1, M = 0..2)') solution{1}=feval(symengine, 'numeric::fsolve',e2-e1,'M')

the output is

solution =

M = 1.0138797382340744030864073818239248

how to get the value of M; which is stored in a 1X1sym.

Thank you very much

Maybe there is another simpler way.

how to use parallel computing for the given code

syms M; 
L = 5.0;A = 1.6;P = 0.0; w = 0.4195; R = 25; PBAR = P/(pi*w*R); 
e1 = A^3 - L*A^2.*(sqrt(M.^2-1) + M.^2.*acos(1./M)) - PBAR; 
e2 = L*A^2/2*(sqrt(M^2-1) + (M^2-2)*acos(1/M)) + 4*L^2*A/3*(sqrt(M^2-1)*acos(1/M)-M+1)-1; 
solution{1}=feval(symengine, 'numeric::fsolve',e2-e1,'M')

i tried with

ms.UseParallel = 'always'

but didnt work (out of 4 cores, 2 cores are only loaded & 2 cores are free)
