Hello Sir,

How can i store different rows of matrix to cells in an cell array. For example: I have a matrix name 'tab' with 5 rows and i want to store every row of 'tab' into different cells of 'v_r' cell array.

tab = magic(5);

v_r = cell(1,5);

Output should be:

Try this:

tab = magic(5);
v_r = cell(1,5);
for row = 1 : size(tab, 1)
    v_r{row} = tab(row, :);
end
v_r % Show in command window
v_r = 1×5 cell array
    {[17 24 1 8 15]}    {[23 5 7 14 16]}    {[4 6 13 20 22]}    {[10 12 19 21 3]}    {[11 18 25 2 9]}

By the way, this just complicates things and is less efficient than just leaving them in a matrix. I would not recommend putting the rows into a cell array.
