Respected Members! My task is to convert RGB image to Blue ratio image.
This is the formula of conversion:
and code is
% RGB to Blue Ratio Conversion %--------------------------------------
R= img(:,:,1);
G=img(:,:,2);
B=img(:,:,3);
BR=((100 * B)./(1+R+G)) .* (256./(1+B+R+G)); % formula for conversion
imshow(BR);
The expected output can be seen in this image after running the code.
But when I apply the code...the output is a black image -- there is no sign of anything in image. Here is the input image:
Kindly help. How I can fix this issue so that I can see the contents of image?

Use your image as it is for further processing or cast it to double using im2double as Image Analyst said.

You need to cast to double because (B+R+G) will get clipped at 255 if you dont and just leave them as uint8!!! Then display with [] option in imshow like Dishant showed you.
