rgb = imread('street2.jpg'); %it is one of the MATLAB examples
[L, a, b] = RGB2Lab(rgb);
%the rest is for presentation, not part of how you use the routine
figure(1);
imagesc(L);
colormap(gray(256));
colorbar();
title('L plane');
figure(2);
imagesc(a);
colormap(gray(256));
colorbar();
title('a plane');
figure(3);
imagesc(b);
colormap(gray(256));
colorbar();
title('b plane');

What do you expect? Matrix for image 'street2.jpg' is saved correctly in variable rgb.

@venmal devi: this time I formatted your code properly, but in future you can do it yourself by selecting the code text and clicking the {} Code button that you will find above the textbox.

What error message are you encountering?
Did you repair your RGB2Lab.m after having deleted the "function" line in your previous work?
