这个程序是基于matlab的计算工件粗糙度的轮廓算术平均偏差Ra的值。里面有例程，还有详细的代码注释，希望对各位有所帮助，代码段还有不完善的地方，日后再改进，但是逻辑应该是没有问题的，大家可以基于此来书写新的程序，算是抛砖引玉吧-This procedure is based on the calculation of the value of matlab workpiece contour arithmetic average roughness Ra of deviation. There are routines, as well as detailed code comments, you would like to help, there are imperfections in the code segment, at a later improvement, but logic should be no problem, we can be written based on this new program, regarded puts it
