Compare and replace elements in matrix

Compare and replace elements in matrix

Compare and replace elements in matrix

(OP)
i have a matrix which has 16 columns and varying number of rows.. i
need to replace the elements ranging from -50 to 50 with zero and the
rest should remain the same.. i have coded for a single element
search and replace which is
 
[m, n] = size(Data);
for i = 1: m
   for j = 1:n
       if ( Data(i,j) == 1 )
           Data(i,j) = 0;
       end
   end
end
 
but how do i do it for a range of -50 to 50 instead of a 1 in my
code.. could anyone help me out.. also please suggest me if there are
any matlab function which does this with out the use of the for
loops...
Regards,
capzos

Is this a homework problem?

(OP)
it isnt a homework.. i am trying some stuff out... which i want to implement completly in matlab with as less number of loops as possible making the complete use of matlab inbuilt function.. but its so vast to read... so i am posting some of the general issues that i come trough.. help me if u could

i think i found the soln for this.. but help me in future
thanks

RE: Compare and replace elements in matrix

I don't do Matlab,  but...  Matlab should be capable of doing something like this:

       if ( Data(i,j) >= -50  AND  Data(i,j) <= 50 )
           Data(i,j) = 0;

DanTex is correct.
