How to remove empty line from struct?

Hello every one

I have struct D with two fields: index

sequence [ ]

D :

1 [1 2 4 5]

[] []

3 [1 2 4 5]

4 [1 2 3 5]

I want to remove the empty line from D and become

1 [1 2 4 5]

3 [1 2 4 5]

4 [1 2 3 5]

thank you

Answer 1

[Walter Roberson]

mask = cellfun(@isempty, {D.index}) & cellfun(@isempty, {D.sequence});
D = D(~mask);

Answer 2

[Yazan]

D.f1 = [1 2 3 4 5];
D.f2 = [];

% structure with 2 fields
D

D = struct with fields:
    f1: [1 2 3 4 5]
    f2: []

% get fields
fields = fieldnames(D)

fields = 2×1 cell array
    {'f1'}
    {'f2'}

% remove empty fields
D = rmfield(D, fields(structfun(@isempty, D)))

D = struct with fields:
    f1: [1 2 3 4 5]

I try this but I got an error:

Inputs to STRUCTFUN must be scalar structures.

I want to remove both fields

Provie your structure array so that I can take a look.

As far as I can tell, this seems to remove empty fields, not rows that are empty in all fields.
