I upload the image with the code of the example and the full quastion. Thank you in advance

One way (Hint):

% Decide any data value within the Image/matrix elements data range (Pixel value) , lets say 100

bw_result=Matrix_data>100
imshow(....)

[Zaid Hyder]

I did that but he said use 'for'end' matrix to answer and I try every I know but did come up with any thing useful

[KALYAN ACHARJYA]

[r,c]=size()
bw_result=zeros(r,c);
for i=1:r
    for j=1:n
        if condition
        result(i,j)=1;
        end 
    end 
end 

.....Complete it, do it yourself ..it's your homework question. Sugesstion to avoid loops, if possible

Thank you, I know it's my home work but my teacher didnt even gave us basic of matlab so all my study on YouTube not that I don't want to answer 😂😂

You can always use this:

for n=1
    bw_result=Matrix_data>100
end

On a more serious note: you may consider doing the Onramp tutorial (which is provided for free by Mathworks). I would also suggest avoiding using the comment style that is only compatible with Octave and will not work on Matlab.
