I've the following cell arrays

keys =
  4×1 cell array
    {'n'    }
    {'key12'}
    {'key13'}
    {'key14'}
values =
  4×1 cell array
    {[   10]}
    {[    1]}
    {[    1]}
    {'Hello'}

When I try to create a struct in the following manner

args=[names;values];
structure = struct(args{:})

the below error occurs

Error using struct
Field names must be non-empty character vectors or a string scalars.
Error in setting.load_setting (line 19)
            structure = struct(args{:})

Could someone please have a look?

在 MATLAB Online 中打开

keys = {'n', 'key12', 'key13','key14'};
values = {10, 1 1 , 'Hello'};
names = {'f1', 'f2', 'f3', 'f4'};
 
args=[names;values];
structure = struct(args{:})

Seems to work for me

Perhaps you are trying with

names = {'f1', 'f2', '', ''};

This will cause problems. If you must proceed this way I think it would be better to replace those empty cells with some string

keys = {'n', 'key12', 'key13','key14'};
values = {10, 1 1 , 'Hello'};
names = {'f1', 'f2', '', ''};
% get locations of empty cell elements
idx = cellfun('isempty',names);
[row, col] = find(idx);
% replace those empty cells with some string
for jj = 1:1:size(col,2)
    idx = col(jj);
    names{idx} = ['skip' num2str(jj)];
end
% Now concatenate cells
args=[names;values]
% convert to struct
P = struct(args{:});
struct2table(P)
