I am getting error matrix demension does not agree

RGB =imread('mammogram.jpg');
hsv=rgb2hsv(RGB);
imshow(hsv);
i= 1:20:120;
r1=0.1;
r2=0.85;
s=0.8;
wgray=1-s^(r1*(255/i)^r2);

in line 5 i want to input value of i from 1 to 120 with diffference of 20

thanks

wgray = 1 - s.^(r1*(255./i).^r2);

Thanks so much sir... I exactly got want i want thanks once again

[kalyani ohri]

if i want to enter the value os s from 0.0 to 1.0 then wgray???

[Walter Roberson]

s = 0:0.05:1;   %for example
wgray = 1 - bsxfun(@power, s(:), (r1*(255./(i(:).')).^r2) );

The result would be length(s) by length(i)
