how to choose the intended answer of an equation that has 4 solutions?

hi, i used vpasolve to solve an equation that has 4 solutions but the problem is i need the one that is between 0 and 1.

how can i choose that one?

M2=vpasolve((((1+1.4*M1^2)/(1+1.4*M2^2))^2*((M2/M1)^2)*((1+0.2*M2^2)/(1+0.2*M1^2)))-(To2/To1),M2);

its because i need to put that one value in another equation.

Provide the missing values to test.

What if the any of the solution lies between 0 & 1 like it does now???

Answer 1

R = double(M2);
Wanted = R(R>0 & R<1)
