clc
source= imread('testimg.jpg');
[rows,coloumn,channels]=size(source)
% Scanning row & coloumn wise
a=1;
while a>=1 && a<=rows
[b]=1;
if b>=1 && b<=coloumn
if source(a,b,3)>=100
% Need help in saving this to specific coloumn in form a vector!
xlswrite("data_oel.xlsx",b,'data','(B2:B169)')
end
b=b+1;
end
xlswrite("data_oel.xlsx",a,'data','(A2:A300)')
a=a+1;
end

See attached demo where I write R, G, B, x, y to a CSV file. Is that what you want?

You can use the max function
rgbImage = imread('peppers.png');
[r, g, b] = imsplit(rgbImage);
maxR = max(r(:))
maxG = max(g(:))
maxB = max(b(:))
