Entropy is a thermodynamic property that can be used to determine the energy available for useful work in a thermodynamic process, such as in energy conversion devices, engines, or machines. Such devices can only be driven by convertible energy, and have a theoretical maximum efficiency when converting energy to work. During this work, entropy accumulates in the system, but has to be removed by dissipation in the form of waste heat.

将时域信号进行处理得到加速度频域幅值谱或振级谱(Acceleration amplitude spectrum or magnitude spectrum in frequency domain can be obtained by processing time domain signals.)

UWB bpsk调制方式下的matlab实现过程，很实用(UWB bpsk modulation matlab under the implementation process, it is useful)

This function creates text objects that mimic x and y tick labels, while the original tick labels are removed. The text object format allows more modification (such as color, rotation, etc) than the original tick labels, and also allows TeX strings to be utilized in tick labels (see xformat and yformat inputs for more details).
