计算临界转速的小程序，考虑了轴的分布质量，但是不包括振型(Calculated critical speed of small programs, considering the quality of the axis of the distribution, but does not include the vibration mode)

harris角点检测，并且可以有效的删除一部分密度较大的点(harris conner detection)

bfgs算法中需要用到的步长规则嗬嗬嗬嗬(the BFGS method)

I want to find out how to use SURF code in MATLAB to detect SURF features and number of matched points between two images. I found the following package OpenSURF_version1c which you can download from

多传感器数据融合的梯度下降法。方法较为简单，代码基本可以实现滚转角与俯仰角的解算，需要再调参数会更精确(Multi-sensor data fusion gradient descent. The method is simple, basic code can roll angle and pitch angle of the solver, you need to re-tune the parameters would be more accurate)

I forgot the name of codes
