Add names to table variables from a large cell

3 views (last 30 days)
I have a 1x72 cell with name like 'Var_name'
Var_name = {[1,3,4],[4,7,8],[1,2],...,[4,6,7],[5,6,8]}; ---> 1x72 cell
and have a matrix A
A = [4 1 0 0...; 5 0 1 1...; 6 1 0 1...; 7 0 1 0...; ...]; ---> 10x72 double
I would like to have a Table that has variable names based on the above cell with Var_name, like this...
index [1,3,4] [4,7,8] [1,2] [4,6,7] [5,6,8]
4 1 0 0 ...
5 0 1 1 ...
6 1 0 1 ...
7 0 1 0 ...
. . . .
I used this code, but it does not work
Var_name_string = cellfun(@(a)string(a),Var_name,'uni',0);
T = array2table(A.','variablenames',{'index' Var_name_string});
instead of ---> T = array2table(A,'VariableNames',{'index' '{1,3,4}' '{4,7,8}' '{1,2}' ....'{4,6,7}' '[5,6,8]'});

% Fake data:
V = {[1,3,4],[4,7,8],[1,2]};
A = randi(9,5,4);
% Create table:
F = @(n)sprintf("{%s}",join(string(n),","));
T = array2table(A,'VariableNames',["Index",cellfun(F,V)])
T = 5×4 table
Index {1,3,4} {4,7,8} {1,2} _____ _______ _______ _____ 6 5 5 1 4 4 2 7 3 7 6 7 3 2 2 1 9 6 3 1

I have this Var_name
Var_name = {[1,3,4],[4,7,8],[1,2],...,[4,6,8,9,11,18,19,20,21,22,23,24,25,30,31,32,34,35,36,40,41,42,56]};
So, I got this error
Error using array2table (line 81)
'{4,6,8,9,11,18,19,20,21,22,23,24,25,30,31,32,34,35,36,40,41,42,56}' is
longer than the maximum allowed length for a table variable name.
Is there any way to fix it?

"Is there any way to fix it?"
Use a shorter name.
