MATLAB Function for Nonlinear Inequality Constraints: c2f1a

This function defines a system of nonlinear inequality constraints. The input vector 'x' has two elements. The output vector 'c' contains one element, which represents the inequality constraint. The vector 'ce' is empty, indicating that there are no equality constraints.

The inequality constraint is given by:

c = 4*x(1)^2 + x(2)^2 - 4

This constraint restricts the values of 'x' such that 'c' must be less than or equal to zero for the constraint to be satisfied.
