很多的都想用自已的和序控制自己的电脑,这里有一些常用函数,希望对大家有用(Many want to use their own and the sequence to control their own computer, here are some commonly used functions, in the hope that useful to everybody)

Tutorial of filter: design a lowpass FIR filter of cutoff requency 0.3*pi. Plot the impulse responses h(n) and magnitude responses of the designed filters

Eigenfaces is used to representing a face by projecting original images onto a face space defined by eigenvectors, and then a new face is compared to known faces by calculating the distance between their projections onto face space. (Eigenfaces is used to representing a face b y original projecting images onto a face space d efined by eigenvectors. and then a new face is compared to known faces by c alculating the distance between their project ions onto face space.)
