PCA

运用matlab进行快速ica变换，对信号进行预处理(Ica using matlab rapid transformation, the signal preprocessing)

This function alculates Fourier Amplitude spectra of the time series of uncorrected acceleration and velocity depending on the FFTformat argument and produce a plot.Visual inspection of the fas is helpful for setting a low cut frequency in filter design and implementation.

是改进平方根法和平方根法的matlab小程序可以学习用的(Is to improve the square root law and the square root of the matlab can learn to use a small program)

SegyMAT is a set of m-files that aims to ease importing and exporting SEG-Y files from Matlab. SegyMAT aims to: completely support SEG-Y revision 1 be easy to use in other projects be compileable using the Matlab Compiler be a Swiss Army knife dealing with the SEG-Y format in Matlab. SegyMAT is not lightning fast. SegyMAT makes heavy use of ’structures’. Unfortunately structures are not very effective in terms of speed in Matlab. (Or they have not been implemented very effectively in SegyMAT). However structures make the implementation and maintainance easier, and the code (hopefully) easy to read. That said, some effort has been made to optimize SegyMAT for speed. The latest version of SegyMAT is always available from Sourceforge : http://segymat.sourceforge.net/.
