Want to use 'solve' with non symbolic variables

Lets say I had the equation:

ax^2+bx+c=0 (the real one is more complicated) and I wanted to get numeric solutions for x with given values of a b & c, but these values change constantly in the program. How could I use solve for this.

Thanks,

Chris

syms a b c
soln = matlabFunction(solve(a*x^2+b*x+c,x), 'vars', [a b c]);

Now call soln() passing in your numeric values for a, b, and c.

Warning: watch out for the fact that solve() might return multiple solutions!

That works great, thank you for your help
