matlab中conv( )就是做卷积，简单理解其实就是多项式乘法。 例如:A=[1 2 3],B=[1 1]是两个向量，A和B的卷积计算方法如下： 把A的元素作为一个多项式的系数，按升幂排列，则对应的多项式为：1+2x+3x^2. 把B的元素也作为多项式的系数，按升幂排列，对应的多项式：1+x。

20.09.2020 · In matlab for convolution ‘conv’ statement is used. The convolution of two vectors, p, and q given as “a = conv( p,q )” which represents that the area of overlap under the points as p slides across q. Convolution is the most important technique in Digital Signal Processing.

N-D convolution, returned as a vector, a matrix, or a multidimensional array. If A and B have the same number of dimensions, the full convolution C = convn (A,B) has size size (A)+size (B)-1. When one or both of A and B are of type single, then the output is of type single . Otherwise, convn converts inputs to type double and returns type double.

w = conv (u,v) returns the convolution of vectors u and v. If u and v are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. example. w = conv (u,v,shape) returns a subsection of the convolution, as specified by shape . For example, conv (u,v,'same') returns only the central part of the ...
