MATLAB: Reverse an array by for loop

for loopreverse

Hi i got this array : a=[1 2 3 4 5] and i want to reverse it by for loop so it will be a=[5 4 3 2 1]

Thanks

Why a for loop?

 a = [1 2 3 4 5] ;
 b = fliplr(a);

If you must with a for loop

for ii = 1:length(a)
   b(ii) = a(length(a)-ii+1);
end

MATLAB: How can I have all the for loop outputs in one matrix

ii=1:3 numel(b);
iwant=zeros(length(ii),1) ;
i=0;
for ii=1:3:numel(b)
 i=i+1;
 iwant(i)= b(ii);
end

Without loop:

iwant=b(1:3;numel(b));

MATLAB: What is wrong with the For loop

A = input('Enter your matrix: ')
for ii = 1:size(A,1)
   for jj = 1:size(A,2)
      if A(ii,jj) > 0
          A(ii,jj) = 2*(A(ii,jj));
      else
          A(ii,jj) = 3*(A(ii,jj)) ;
      end
   end
end

You are running loop only along the number of times the row's are. Now I have included columns also.

You can achieve the same without loop.

B =A ;
B(A>0) = 2*A(A>0) ;
B(A<0) = 3*A(A<0) ;
