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] ...
Ifa(1)is not equal to1, thenfilternormalizes the filter coefficients bya(1). Therefore,a(1)must be nonzero. Ifxis a vector, thenfilterreturns the filtered data as a vector of the same size asx. Ifxis a matrix, thenfilteracts along the first dimension and returns the filtered data for...
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. ...

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: ...

Using the polyphase method to create a matrix of the filter's coefficients. Export the Polyphase Filter to an Object. To export a polyphase filter to an object in the MATLAB workspace, complete the following steps. In filter designer, open the File menu and select Export... This opens the...
Filter the data inAaccording to a filter coefficient matrixH, and return the full matrix of filtered data. H = [1 2 1; 0 0 0; -1 -2 -1]; Y = filter2(H,A,'full'); mesh(Y) RotateH180 degrees and convolve the result withA. The output is equivalent to filtering the data inA...
