How can I construct the array problem?

Help with this matlab problem, i don't know how to assign values to the array?

• This is the question Check every elements inside the second column of Test Data. If the values are greater than 0.5 assign them to array 'A'. If they are less than -0.5 assign them to array B. Other wise assign them to array 'C'. and this is what i have so far, but its not working and i dont know what to do. S= load('/Users/Stayout/desktop/test.txt'); X= S(:,2); A=[]; B=[]; C=[]; for i=1:length(X); if(X(i)>=.5) X(i)= A; elseif (X(i)<=-.5) X(i)= B; else X(i)=C; end end disp (A) disp (B) disp (C) pleaaassee help!!!

• Answer:

  Try this in the central part... for i = 1 : length(X); if (X(i) >= .5) A(i) = X(i); elseif (X(i) <= -.5) B(i)= X(i); else C(i) = X(i); end A B C If you need more examples with Matlab, I suggest you visit the site below. It's for beginners... Good luck!
