三维数字滤波器中的理想低通滤波器的matlab仿真及其结果(3 d digital filters in an ideal low-pass filter matlab simulation and the result)

说明：  附带详细说明，内容，具体情况，讲解包含很多问题(QWQDDSDSDWDDWDWDDWDWDW)

根据毕奥-萨伐尔定律推导了运动电荷产生的磁感应强度的公式，用曲面显示运动电荷产生的磁感应强度的分布规律。 通电线段的磁感应强度公式 磁感应线的半径形成等比数列，精确显示了二维磁感应线(Derivation based on the Biot- Savart law of magnetic induction generated by the moving charge formula, the distribution of magnetic induction surface display generated by the moving charge.)

QAM系统的全数字设计，学位论文，较长较细致，值得参考，不多说，免费下(QAM system, all-digital design, dissertations, longer than the detail, it is also useful, not more than that under free)

This Code compute the Mahalanobis distance between two gussian distribution.

图像分类。将图像中的40个样本作为训练样本，训练得到分类器，将另外160个样本作为测试样本测试分类器的效果。(Image classification. The image of the 40 samples as training samples, the trained classifier, an additional 160 samples as a test sample test classification results.)

看了一段时间的3GPP的信道建模，所以自己动手写了一个（参考了该协会的标准代码，不过改良了一些，执行效率更高）(the 3GPP SCM model building. Comparing to the original code, this task is more efficient and clearer.)
