Why isn't one image white and the other black according to my code

1 view (last 30 days)
>> b=255*ones(78);
>> figure,imshow(a);
>> figure,imshow(b);
If I run the above code then one image should be bright while the other dark(I am using uint8 thus range is 0-255) but the fact is both turn out to be white. May I know why ?

You don't cast anything as being uint8. Try:
figure, imshow(uint8(a));
then it will be black
