If you introduce slack variables to convert your inequalities to equalities, you can also use fsolve.
That means:
If you have a set of inequalities of the form
f(x) <= 0,
you introduce new variables y and solve
f(x) + y.^2 = 0.

Use fmincon instead of fsolve. Simply set the objective function to 0 and use fmincon only to determine a feasible point of your problem.
