## Does the solve command in MATLAB not give you an answer?

In a recent blog about the MATLAB solve command, I mentioned that the solve command was not giving us the unique real solution to a physical problem. A user at MATLAB suggested declaring the syms variable as real, before using the solve command. That worked. So if the equation in terms of the variable *b *is eqnb=0, then use

syms b real;

solve (eqnb,b);
