How to create matrix from multiple vectors?

Hi everyone,

I read a database image, it includes many images. I describe each image with a vector have to size is 8400 x 1. Thus, I have multiple vectors.

Now, I want to arrange them for one matrix.

Please help me. Thank you so much.

clc;
clear all;
srcFile = dir('C:\images\*.jpg');
for i = 1:length(srcFile)
    filename=strcat('C:\images\',srcFile(i).name);
    img=imread(filename); % read 1258 images
    img1 = img(:); % image to vector
    %%How to arrange 1258 vectors (img1) become matrix?
end

Matrix is also vector, you can concatenate them as new matrix

result=[vec1;vecc2;vecc2....]

Result size: Number of vector concatenated*8400x1

or

result=[vec1,vecc2,vecc2,....]

How you concatenate depends of required size of result matrix

Result size: 8400x1*Number of vector concatenated

Dear KALYAN,

Thank you for your support.

Howewer, Number of vectors are 1258. I can't use your suggest command.

I just provided, how the thinks works. You can use concatenate arrays within a loop,check here
