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

extract data from 1x1sym

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.
