MATLAB Online에서 열기 I have a matrix [8x3] and a vector quantity that's [6x1]. What I'm trying to do is pick out the three values from the vector within the matrix. Here is the code I'm running. x=[1;2;3;4;5;6] ...
If a(1) is not equal to 1, then filter normalizes the filter coefficients by a(1). Therefore, a(1) must be nonzero. If x is a vector, then filter returns the filtered data as a vector of the same size as x. If x is a matrix, then filter acts alon...
If x is a matrix or multidimensional array, then zf is an array of column vectors of length max(length(a),length(b))-1, such that the number of columns in zf is equivalent to the number of columns in x. For example, consider using filter along the second dimen...
y = filter(b,a,x,zi,dim) acts along dimension dim. For example, if x is a matrix, then filter(b,a,x,zi,2) returns the filtered data for each row. example [y,zf] = filter(___) also returns the final conditions zf of the filter delays, using any of the previous syntaxes. ...

Y = filter2(H,X) applies a finite impulse response filter to a matrix of data X according to coefficients in a matrix H. example Y = filter2(H,X,shape) returns a subsection of the filtered data according to shape. For example, Y = filter2(H,X,'valid') returns only filtered data...
filter是一维数字滤波器。使用方法：1、语法：filter函数是一维的数字滤波器，主要的应用语法如下所示 y=filter(b,a,X)[y,zf] = filter(b,a,X)[y,zf]=filter(b,a,X,zi)y=filter(b,a,X,zi,dim)[...]=filter(b,a,X,[],dim)y=filter(b,a,X)滤除向量X中的数据，其中b是分子...
这里给出一种最原始的实现方案。这样的实现对于数据矩阵大小为1000x1000,卷积核矩阵大小为20x20,在我的机器上须要大约1秒钟的时间。而matlab採用的MKL库最快仅仅须要将近0.1s的时间。 以下的代码用到了自己眼下开发的FastIV中的一些函数接口。详细代码例如以下: ...
