design the function function t_hat= perceptron_predict(x, map_func, theta). the function returns the perceptron output t_hat, as a column vector of hard predictions applied to inputs in matlab

main.m
function t_hat = perceptron_predict(x, map_func, theta)
% perceptron_predict calculates the perceptron output as a column vector of hard predictions
% for a given input vector x, map function and theta.

% x: input vector
% map_func: the mapping function
% theta: a column vector of the perceptron weights

% Output:
% t_hat: predicted output value

% calculate the output value
output = map_func(theta' * x);

% binary hard prediction
if output >= 0.5
  t_hat = 1;
else
  t_hat = 0;
end
