用双线性变换法设计IIR数字滤波器 滤波就是将外界干扰的不需要的频率滤除掉，一面影响要测试数据的结果。比如如果是心电波的话，如果这是外界有很大的噪声干扰，滤波就是把不必要的信号给抑制掉，以便对心跳的正常测试。通过图比较，滤波后的明显比之前的要平滑，就是滤去干扰噪声的结果。采样间隔对实验有影响，取的过大会导致频率混叠。(Bilinear transformation method using digital filter IIR filter design is to outside interference filter out unwanted frequencies, while the impact to test data results. For example, if it is so heart waves, if this is a great noise outside interference, filtering is unnecessary signal out to the curb in order to test the normal heartbeat. Through chart comparison, after filtering than before to smooth the noise interference is the result of least squares. Sampling interval of the experiment affect take-off frequency of the General Assembly leading to aliasing.)

对加速度传感器采集的加速度数据进行二次积分，得出位移数据，并在几分过程中进行积分基线的标定，较精确。(The acceleration of acceleration sensors to collect data, a second integral part of displacement data, and in the process of integration, the more precise the baseline calibration.)

实现DV-Hop定位算法的仿真,自动生成一定节点数的随即分布图，给出仿真结果的各点定位误差，用曲线图形显示，并可以计算平均误差。(DV-Hop simulation. Produce a randomly distributed nodes and then simulate and give the location error of each node, showing it in figure, and calculate the average error. )

源码关于多目标灰狼优化的，还有实例(Source for multi-target wolf optimization, and examples.)

Digital Image Processing With MATLAB

本程序主要是利用小波多分辨率的特点对图像进行压缩。(image compression based on wavelet transform)

Given signal-to-noise ratio and bit error rate performance curve is a good beginner s reference program.
