二分法 插值 通过每次把f(x)的零点所在小区间收缩一半的方法，使区间的两个端点逐步迫近函数的零点，以求得零点的近似值(Each time the interpolation dichotomy by f (x) between zero shrinkage area where half of the ways in which the two endpoints interval function gradually approaching zero, in order to achieve an approximation of zero)

说明：  根据历史电网负荷数据，用深度置信网络预测未来负荷大小(Forecast future load size based on historical grid load data)

matlaba写的ahp层次分析法小程序 还有注释 经测试无误 欢迎下载(ahp software)

说明：  说明了matlab与cuda之间的关系，对于有一定基础的matlab编程人员来说，是一个可以借鉴的书(Matlab and cuda illustrates the relationship between the basis for some of the matlab programmers is a reference book)

使用MATLAB编程，求非线性方程组的根。本例为三个参数的非线性方程组。(Using the MATLAB programming, seeking the roots of nonlinear equations. In this case, there are three parameters.)

利用logGabor函数分别提取待匹配图和模板图的相位信息作为匹配基元，进行互相关运算，寻找最佳匹配位置(Use to be extracted separately logGabor function map and template matching of the phase diagram as an information matching primitives to carry out cross-correlation calculation, find the best match position)

编程产生一组随机的0、1二进制比特序列，分别用2ASK, 2FSK, 2PSK和2DPSK四种调制方式把它们调制到一个较高的载频上，调制参数自定，请给出前8个比特所对应的时域波形。 画出上述四种信号通过高斯白噪声信道后的相干解调器和非相干解调器的原理框图，并给出判决前的观测值的数学表达式。注: 如果某些调制方式无法进行非相干解调，请给出原因。 根据题2中的观测值的数学表达式，分别编程实现判决过程，将判决结果与原数据作比较，统计出各自在不同比特信噪比 值下的误比特率 ，然后画出 与 (dB)的曲线。建议 的范围为 0dB 到10dB, 以1dB为间隔。 将上述仿真得到的误比特率曲线与各自的理论值画在同一张图上进行比较并讨论。同时， 比较和讨论不同调制与解调方式的差错性能区别。(emulate 2ASK, 2FSK, 2PSK and 2DPSK using matlab)
