如何将 uint8 转换为单个？ MATLAB

Question

I have an array with 384x255 uint8 contains the features of an image, I want to train this image by using svmtrain . How to convert this array to 1-by-N single matrix so the number of rows will be equal to label .

---

I will explain my problem, I have extracted HOG features for ~500 images and saved results in a matrix.. easily, this matrix consist of 500 rows, each row has a HOG feature of one image. BUT when I tried to extract LBP feature every thing is different. The matrix is about 384x255 uint8 for each image (I have ~500 images). I make reshape for this big matrix to be 500 rows, each raw has LBP features of an image but after classification them by SVM classifier, the results was terrible. So, does reshaping and converting from uint8 to single may change data and effect results?

假设您的数组存储在A ：

B = reshape(single(A), 1, []);
