Steady compressible Euler equations in 2 dimensional channel with bump

机器学习中用到的梯度下降方法，凹凸性判读资料-Gradient descent method used in machine learning, data interpretation uneven nature

This code was made to draw streamline passing through bump located in the right-belowed of 2-d rectangular field. User can execute the file by typing ./Make_and_Execute ,and then you can have your own outfile changing input parameters prescribed in
