For the following examples, first draw the scatter plot of the data. Then, design a perceptron neural network and obtain its parameters by the perceptron learning algorithm.

input matrix: $x=\left[\begin{array}{cc}-1& -1\\ -1& 1\\ 0& 0\\ 1& 0\end{array}\right],D=\left[\begin{array}{c}1\\ 1\\ 0\\ 0\end{array}\right]$
