This is a multi-objective optimization problem.

The Global Optimization Toolbox might be what you're looking for. If you weren't interested in applying any constraints, your code might look like:

fitnessfcn = @(x)(polyval([1, 6, 8], x)) % quadratic fitness function
[x, fval] = ga(fitnessfcn, 1) % evolves to a local minimum

x is a locally minimizing input to fitnessfcn, and fval is the associated output. Since you're dealing with a function with -Inf as the global minimum, you may want to apply constraints. See http://www.mathworks.com/help/gads/ga.html for the full reference.

thanks for your answer.

My equation is : 2x^3+3x^2+3x+1=0

i wanna finding the roots of the above equation .

can find them with your code?
