How to save Data Individually

I Have a Data

like 2000*5 i.e 2000 rows with 5 colomns.

I would like to save this the data in to five varaible like x1,x2,x3,x4 and x5 where x1 consisting of 1st coloms of x.

The MATLAB code must be any loop function.How to Write and save 2000*1 data of 5 different variables using a loop statement with MATLAB

"I would like to save this the data in to five varaible like x1,x2,x3,x4 and x5"

That is very unikely to be a good approach:

You can simply access the data directly from the matrix using basic indexing, or split the matrix into a cell array:

C = num2cell(M,1)

Thanks for the answe

For the reason @Stephen mentioned. Only way to create variables in a loop is using eval function.

It is bad to use eval to create variables in loop.

So, you can do it manually like

x1 = x(:,1);

x2 = x(:,2);

....

Or in a loop to store in a cell

for i=1:size(x,2)

x_cell{:,i} = x(:,i);

end

Or just use num2cell

x_cell = num2cell(x,1);

Thanks for the Answer,But This is my data in data_beffer1,it is of 8000*5 size .Now I would like to give name to each column where size of the each column must be 8000*1 size with loop statement

[Stephen23]

"Now I would like to give name to each column..."

Then use a table:

M = rand(8000,5);
T = array2table(M, 'VariableNames',{'a','b','c','hello','world'})

T = 8000×5 table
        a           b           c         hello       world
