The command for generating gaussian filter in Matlab is:
【 在 nevermind (剧中人) 的大作中提到: 】
: Guassian filter can be generated in matlab by one function. I forgot its name.
: try guassian or something like it.
: In fact, any vector can be a filter such as :[.1,.3,.9,.3,.1] and you have to
: normalize it, of course. for low pass filters, big elements in the middle,
: small ones on both sides. for high pass, reverse.
: tell more why your @ point is the answer. there must be a prior knowledge to
: find the answer. you can't just give some data and segment it, i think
: 【 在 alanshou (maverick) 的大作中提到: 】
: : I do not know Gaussian low pass filter. What I learned from Signal & systems
: : about the lowpass filter is Chevbey and Butterworth filter,and elliptic
: : filter. And it is very easy to construct them in Matlab. Just five or sive
: : line command.And you can also convert them into highpass, bandpass, or
: : bandstop easierly! If that can help, tell me. I can help you on them.
