I have created a 50x50 pixel matrix, in which each 'pixel' has been assigned 3 random values between 0 and 255. When I visualize the image using image(), a figure that is mostly white appears, and the colors that are shown are incorrectly represented. I examined some of the white pixels and saw that they did indeed have RGB values associated, and I know that the resulting color should not be white. The code I used to create the image is shown below. Any help would be greatly appreciated.
clear;
width = 50;
height = 50;
W = zeros(height,width,3);
for i=1:(height)
for j=1:(width)
W(i,j,1) = randi(256)-1;
W(i,j,2) = randi(256)-1;
W(i,j,3) = randi(256)-1;
end
end
I realized that I needed to normalize the RGB values.

You need to convert it to uint8 from double. Also no need to use for loop. Following code will work more efficiently.
image(uint8(randi(256, 50, 50, 3)))
