Importing and RGB image to matlab in the form image L(x,y)=[LR​(x,y),LG(x​,y),LB(x,y​)]

So i'm wondering how i take an RGB into matlab and split it into the following format:

image L(x,y)=[LR(x,y),LG(x,y),LB(x,y)] let us

im = im2double(imread('test_images\low_light\8.bmp'));

Error using imread>get_full_filename (line 569)
File "test_images\low_light\8.bmp" does not exist.

Error in imread (line 371)
fullname = get_full_filename(filename);

the above line of code spits out a value 365x490x3 double which i assume x = 365 y = 460 and 3 = the RGB colours associated with the picture.

Any idea how i can produce an output which looks like:

T(x,y) = max(R,G,B) Lc(x,y)

Thanks.

L(x,y) = LR(x,y),LG(x,y),LB(x,y)]

Sorry forgot to add this part

LR=L(:,:,1); % First Slice: Red Component
LG=L(:,:,2); % Second Slice: Green Component
LB=L(:,:,3); % Third Slice: Blue Component

All above are result to three 2D arrays.

Regarding the error:

Please ensure that the image file must be present in the same working directory or specify path properly.
