How do for loop and stop when code is catch error 1e-6, and please i need to check following code to get "M1" Value

for M1=.1:.1:10
    
    e1=0.0045/.00264;
    e2=((2+.135*M1^2)/(2.135))^(2.135/(4*.135))*(1/M1)^0.5;
    
    while abs(e1-e2)~= 1e-4
        continue
        if abs(e1-e2)== 1e-4
            break
        end
    end
end

fprintf('%3u',M1)

Answer 1

e1=0.0045/.00264;
fnF=@(M1)((2+0.135.*M1.^2)./(2.135)).^(2.135./(4*0.135)).*(1./M1).^0.5-e1;
fplot(fnF,[0.1 3])

shows zero crossings around 0.2 and 2

>> fsolve(fnF,0.2)

Equation solved.

fsolve completed because the vector of function values is near zero
as measured by the value of the function tolerance, and
the problem appears regular as measured by the gradient.
