Dear all,

I have one array that includes 5 binary images [I1, I2, I3, I4, I5].

I want to have a new array [R1, R2, R3, R4] where:

R1 = I1 + I2

R2 = R1 + I3

R3 = R2 + I4

R4 = R3 + I5

How to make a for loop for that?

Any help will be very appreciated.

Thank you very much.

Meshoo

Try this:

R1 = int32(I1) + int32(I2);
R2 = R1 + int32(I3);
R3 = R2 + int32(I4);
R4 = R3 + int32(I5);
output_R = [R1, R2, R3, R4];
imshow(output_R, []);  % The [] are important.

Thank you very much. Your program will add all the binary images, but actually I want the flow of the program to be in the same way I explained before, because I am doing other operations (adding the binary was just an example).

So how to make a new array R[ ] that contains four binary images R1, R2, R3, R4.

R1 = I1 + I2

R2 = R1 + I3 % do something

R3 = R2 + I4

R4 = R3 + I5

Not a good idea. Remember you said "Sometimes I have 100, 120, etc." So now I refer you to the FAQ about why this is a bad idea: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F

Here is how to make a loop for that:

 R(:,1)=I(:,1)+I(:,2); %Initialization
 for i=2:4
   R(:,i)=R(:,i-1)+I(:,i+1); %This is the loop that you asked for.
 end

Thank you all for your comments. Is there some way to do it directly without any reshaping?
