How to create matrix from multiple vectors?

246 views (last 30 days)
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

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