Thank You Torsten.

Is there any way to solve these equations using fsolve.

[Torsten]

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.
