The conv2 function allows you to control the size of the output. Create a 3-by-3 random matrix A and a 4-by-4 random matrix B. Compute the full convolution of A and B, which is a 6-by-6 matrix. Get A = rand(3); B = rand(4); Cfull = conv2(A,B) Cfull = 6×6 ...

在MATLAB 中,filter2函数实现二维数字滤波器.conv2函数实现二维卷积. filter2(H, X, mode)等价于conv2(X, rot90(H,2), mode). 其中,H表示有理传递函数的系数(Coefficients of rational transfer function),即常说的滤波器核或卷积核.X表示输入数据.mode表示卷积或滤波所采用的模式,其决定了返回数据的长度,以...

conv2不支持整型的参数，用conv2之前先把参数用double()给转换成浮点数。例如如果你原来要代入conv2的参数为a和b 那就 a=double(a);b=double(b);conv2(a,b)f0

卷积可以通俗地看成：你写成小学生算的乘法。注意这个是不进位的。___123 ___012 === ___246 __123 _000 === _01476 这个就是你上面的结果。matlab自带的function browser
