I’m reading an image teste.jpg by command imread and turn it into a gray image by the command rgb2gray. I need the corresponding codes of the result of this matrix, in a file .txt.
Follow the Example:
A = imread ('alta-fauna15.jpg')
B = rgb2gray (A)
imshow (A) // Mostra Imagem colorida
imshow (B) // Mostra Imagem em escala de cinza
I need those matrix values B in an archive .txt, how can I do this?

An easy way to do is by transforming the 8-bit image unsigned integers to double, and saving using dlmwrite().
A = imread ('alta-fauna15.jpg')
B = rgb2gray (A)
imshow (A) % Mostra Imagem colorida
imshow (B) % Mostra Imagem em escala de cinza
dlmwrite('myFile.txt',im2double(B)); % Salva e converte
C=dlmread('myFile.txt'); %Le o arquivo
C=imshow(C) %Mostra Imagem em escala de cinza
D=im2uint8(C); %Converte novamente para 8-bit unsigned integers
