Matlab program to plot the data acquired from the USB (and placed into a TXT file) for the NIA device (Neuro impulse Actuator)

it just show the different type of signals and their matlab codes

选择不同的两个函数做卷积运算，可供选择的函数有矩形窗函数，锯齿波函数和sinc函数，也可自行选择其他窗，观察选取函数的波形。(Choose a different function to do convolution function to choose a rectangular window function, ramp function and the sinc function, to choose the other window, observe the waveform of the selected function.)

原信号分解成IMF后，用此脚本来计算此IMF的瞬时频率(After the original signal into IMF, use this script to calculate the instantaneous frequency of the IMF)

主要是基于KSVD的稀疏编码去噪的算法，属于matlab版的，里面有我个人的所有注释！(Mainly based on the sparse coding KSVD denoising algorithm, belong to matlab version, there are my personal all comments!)
