MATLAB: Converting all array elements into positive elements

converting all array elements into positive elements

I have an aray like this:

A=[1 -3 -1 4]

I would like to have the same elemnt but with all elements have been converted to positive

Then,

A=[1 3 1 4]

Any suggestions? Thank you in advance.

A = abs(A)

squeeze()

A=[1 2;4 3]  %edited
[m,n]=size(A);
result=cell(1,m);
for i = 1:m
result{i}=[A(1,i).*(A)];
end
result=horzcat(result{:})
