how can i save row value in variable like x(1)

i have metric row =[1 1 0 0; 1 1 0 0; 0 1 1 0 ; 1 1 0 0] how i can make x(1)=1 1 0 0 and x(2)= 1 1 0 0 and so on

Answer 1

[Andrei Bobrov]

>> row =[1 1 0 0; 1 1 0 0; 0 1 1 0 ; 1 1 0 0] ;

x = row;

x(1,:)
ans =
     1     1     0     0
>> x(2,:)
ans =
     1     1     0     0

can i make for loop and write

 for i=1:4
   x(i)=.......

i mean x(1)=1 1 0 0

Answer 2

[Walter Roberson]

What you ask is not possible in MATLAB. You two options (using a for loop) are:

for i = 1 : 4
  x(i,:) = row(i,:)
end

or

for i = 1 : 4
  x{i} = row(i,:);
end

In the first of those options, you would need to access x(1,:) to get the first row as a numeric vector.

In the second of those options, you would need to access x{1} to get the first row as a numeric vector. Notice that is not x(1), it is x{1}. If you were to use x(1) then what you would get would be {[1 1 0 0]} which is a cell array containing the vector rather than the vector itself.
