Alternative to "solve" command for faster computation?

Hello, is there an alternative approach to solve-command when computing 3 unknown variables out of 3 equations? Specifically, I have 3 points (X coordinates) lying on a curve and I want to get the radius of this curve (using the analytic circle equation). It actually works with solve but the problem is that I do this in a loop where the computation time is crucial, according to the Run&Time solve seems to be the largest source of the time delay.

Thank you for your hints

solve() once will symbolic variables, either before the loop or while you are designing the program. Use matlabFunction() to turn the symbolic version into a function handle of a numeric function (or to write the function to a file.)
