HHTcode

在同温度和和照度下，n改变时，光生电流不变。(when the temperature and irradiation are the same the output photocurrent Iph of the same piece of solar cell remains constant although the diode quality factors and reverse saturation currents are different.)

用canny算子实现对图像边缘的检测，效果比较好。在经典算法上进行的改进(Canny operator image edge detection, the results were quite good. Improvements in the classical algorithm)

this is a useful method of realizing prony in matlab system
