please help me code these on matlab

8. (Relational Operators) Relational operators can be used to compare vectors to each other provided sizes match) or to scalars and produce vectors of logical values. This can be useful for deciding which inputs satisfy a certain requirement. in_unit_disc Function: Input parameters: two vectors representing a set of (:2, y) coordinates in the plane Output parameters: a logical vector where each element is true if the corresponding point in the input satisfies the inequality 2? + y2 > [is_inside] = in_unit_disc( [0 1/2 1], [0 1/2 1]) is_inside = 110 7. (Function Evaluation) Let f(x) be defined by sin (0) f(x) = f_eval Function: Input parameters: a vector representing input values for 2 Output parameters: a vector representing thevalues of f(x) Possible sample cases are: >> [y] = f_eval([0 1 2]) y = 0.00000 0.42074 -0.15136
