超声仿真的代码，matlab的，对于阵元的发射接收的例子，是很好的学习资料。改代码依附于丹麦理工的fieldtwo，可以参考user guide进行仿真。里面是文本格式的，打开转成.m文件即可(Of ultrasound simulation code, matlab example for the launch of the array element receives a good learning materials. Change the code attached to Danish Polytechnic fieldtwo, can refer to the user guide Simulation)
