No need to use a loop:
{list.name} % to place into a cell array
[list.name] % to concatenate together

Thanks, but length of list is 10 so I want to make name list like 10 by 1(10*1)

vertcat(list.name) % concatenate elements
[list.name].' % concatenate elements
{list.name}.' % place elements into a cell array

That is why I showed you this approach:
{list.name}.'
Much simpler than a loop.

You can make it a cell array.
leng=length(list)
nl = cell(leng,1) ;
for i=1:leng
nl{i}=list(i).name
end
You may access n1{1}.........n1{10}

You can do the same as shown above. Store them into a cell array.

Do you have any idea to make it matrix form not cell array?
