"how can i save all name in matrix form?"

Although you underlined the text "in matrix form", you did not explain how that "matrix form" would be any different to the answers you got to your duplicate question here:

Please show or explain how a "matrix form" would be different from the normal, standard, easy approach of using a cell array.

list=dir('C:\Users\pc\Desktop\*.xlsx');
leng=length(list);
name=cell(leng,1);
for i=2:leng
   name{i} = list(i).name    
end

The above is nothing but:

name = {list.name}

Why? Each name will vary, it is a string. So you have to save it into a cell.
