B = padarray(A, padsize) pads array A with 0's (zeros). padsize is a vector of positive integers that specifies both the amount of padding to add and the dimension along which to add it. The value of an element in the vector specifies the amount of padding to add. The order of ...
iomega_array = 1i*2*pi*(-Nyq : df : Nyq-df); iomega_exp = dataout_type - datain_type; % Pad datain array with zeros (if needed) size1 = size(datain,1); size2 = size(datain,2); if (N-size1 ~= 0 && N-size2 ~= 0) if size1...
To pad with 100 rows of zeros, do the following % to add to the top X_proj_corrected = padarray(X_proj_corrected,100,'pre'); % to add to the bottom X_proj_corrected = padarray(X_proj_corrected,100,'post'); 댓글 수: 1 ...
用法:B = padarray(A,padsize,padval,direction) A为输入图像,B为填充后的图像,padsize给出了给出了填充的行数和列数,通常用[r c]来表示。padval和direction分别表示填充方法和方向。它们的具体值和描述如下: padval:'symmetric'表示图像大小通过围绕边界进行镜像反射来扩展; 'replicate'表示图像大小通过复制外...

1. padarray函数的基本用法 在MATLAB中,padarray函数可以用来将数组进行填充,其基本语法如下: ```matlab B = padarray(A, padsize) ``` 其中,A是原始数组,padsize是一个向量,用来指定每个维度的填充大小。对于一个2维数组,padsize可以是一个长度为2的向量,分别指定x和y方向的填充大小。 除了指定填充大小外...
padarray是MATLAB中用于对矩阵进行填充的函数。它的基本用法如下: matlab B = padarray(A, [m n], padValue) 其中,A是要进行填充的矩阵,m和n是填充的大小,padValue是填充的值。 例如,下面的代码将对矩阵A进行上下左右各填充1个元素,并将填充值设为0: matlab A = [1 2 3; 4 5 6; 7 8 9]; B ...
