访问多个文件夹 matlab 并存储在同一个垫子中

Accessing multiple folder matlab and store in same mat

我是 Matlab 的新手。我有如下代码。如何读取多个文件夹。我知道通过使用循环，但不知何故我用谷歌搜索我找不到它。另外，我在下面写的是 myA 文件夹。如何为 myA、myB、myC 将 featureVector 放在同一个垫子 AllTrain 中？该文件夹包含图像。

% Specify the folder

for k = 1 : length(theFiles)

fullFileName = fullfile(myA, baseFileName);
fprintf(1, 'Now reading %s\

% Now imread the file
imageArray = imread(fullFileName);
imageEdge = edge(imageArray, 'canny', 0.4);

a_inv_mom = Hu_Moments(imageEdge);
format short
a_inv_mom_normal = -sign(a_inv_mom).*(log10(abs(a_inv_mom)));

featureVector = cat(1,a_inv_mom_normal);
AllTrain(k,:) = [featureVector k];

% imshow(imageEdge); % Display image.
drawnow % Force display to update immediately.
