My basic code is :

clc
close all
%%%%%%%%Read an Image + convert into grayscale
fileNames=dir(fullfile('D:\Project\HSV\New Folder\*.bmp')) ;
for k= 1:length(fileNames)           
  img_rgb = imread(['D:\Project\HSV\New Folder\' fileNames(k).name]);
  my_vector = quant_hist (img_rgb);
end

where the fucntion quant_hist is returning me a vector of size[256x1] , in images I am having 3 images , so I want my_vector to be of size [256x3] but it stores only the ast iteration value.

在 MATLAB Online 中打开

fileNames=dir(fullfile('D:\Project\HSV\New Folder\*.bmp')) ;
my_vector=zeros(256,3);
for k= 1:length(fileNames)           
  img_rgb = imread(['D:\Project\HSV\New Folder\' fileNames(k).name]);
  my_vector(:,k) = quant_hist (img_rgb);
end
