conv()函数是用于计算向量的什么和什么?

如题所述

conv()函数是用于计算向量的卷积和多项式乘法。 

【使用说明】:

(1)w = conv(u,v) convolves
vectors u and v. Algebraically,
convolution is the same operation as multiplying the polynomials whose
coefficients are the elements of u and v.

(2)w = conv(...,'shape') returns

a subsection of the convolution, as specified by the shape parameter:

full   

Returns the full convolution (default).

same  

Returns the central part of the convolution of the same
size as u.

valid

Returns only those parts of the convolution
that are computed without the zero-padded edges. Using this option, length(w) is max(length(u)-max(0,length(v)-1),0).

【注】:matlab函数可用help和doc查询用法。

如help conv,doc conv。
