Code for plotting bessel functions

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

自己做的一个DCDC升压电路模型，通过设置占空比可以将电压升高到目标值(DCDC boost)

说明：  计算三者的幅频响,计算三者的相频响应,计算三者的冲激相应,并观察三者冲激响应的能量积累情况(Calculated frequency response of the three sites, calculate the three-phase frequency response, calculate the corresponding three of the impulse and the impulse response observed among the energy accumulation)

说明：  cox回归分析的学习总结资料，包括example。PPT(cox regression analysis of the study summary data. PPT)

说明：  matlab自编迭代法求阈值，并按照此阈值对图像进行二值化处理。(matlab self iterative method for threshold and follow this threshold for image binarization processing.)
