I want reach M2 from this code but i have problems with the solve function, should i use fsolve and how?
clc
clear
syms M2;
L=input('enter the L value\n');
D=input('enter the D value\n');
% P1=input('enter the P1 value\n');
% T1=input('enter the T1 value\n');
M1=input('enter the M1 value\n');
f=0.005;
Ls1=(((1-M1^2)/(1.4*(M1^2)))+((2.4/2.8)*log((2.4*(M1^2))/(2+0.4*(M1^2)))))*(D/(4*f));
disp(Ls1);
M20=0;
% if L<Ls1;
Ls2=Ls1-L;
M2=solve('(((1-M2^2)/(1.4*(M2^2)))+((2.4/2.8)*log((2.4*(M2^2))/(2+0.4*(M2^2)))))*(D/(4*f))- Ls2',M2);
disp(M2);

M2=solve((((1-M2^2)/(1.4*(M2^2)))+((2.4/2.8)*log((2.4*(M2^2))/(2+0.4*(M2^2)))))*(D/(4*f))- Ls2,M2); %?
