两相不对称电机矢量控制和直接转矩控制的比较.(Two-phase asymmetric motor vector control and direct torque control comparison.)

z源逆变器简单升压控制的另一种改进的算法及仿真例程，只需改变占空比即可实现直流侧电压的改变，相对于传统的算法简单，更容易理解。(Z source inverter simple boost control of another kind of improved algorithm and simulation routines, only need to change the duty cycle of dc side voltage change can be realized, compared with the traditional method is simple, easy to understand. )

说明：  用pso对bp神经网络进行优化，对pid控制器进行优化设计(Using PSO to optimize BP neural network and PID controller)

超宽带中的频谱检测算法的MATLAB实现，实用价值高。(Ultra-wideband spectrum detection algorithm in the MATLAB realization of high practical value.)

能够产生高斯白噪声，有色噪声和一般噪声。用于matlab仿真实验。(Generated Gaussian white noise, colored noise and general noise.)

HISTNORM Histogram normalized [...] = HISTNORM(...) works like HIST, but the frequency is normalized so that area sum is 1. Bonus usage! [...] = HISTNORM(..., plot ) plots and returns the output arguments. Be sure plot is the last argument. Example: data = randn (10000, 1) [xo,no] = histnorm(data, 101, plot ) hold on plot (no, normpdf(no), r ) hold off See also: HIST.
