Initialization of array of structure
显示 更早的评论
Hello
I have a created array of structure (named LD) which incrementes from 1 to no of database (eg LD(1) to LD(10)). The structure has some fields. After some time I need to re-initialise the structure.
I tried with following commands.
LD = [];
But, I lost the field names, how to initialise with out loosing the field names.

Experiment with
LD = LD(false);

Yes, that is fine.

For the clearing, you might be able to use
LD(:) = [];
Unfortunately I cannot test that at the moment.

You shouldnt do LD=[], instead you should change the field of each of the structure in the array.

The following code should do the trick:
function is = StructInit(s)
is = s;
if isstruct(s)
f = fields(s);
for i = 1 : length(f);
if isstruct(is.(f{i}))
is.(f{i}) = StructInit(is.(f{i}));
else
is.(f{i}) = [];
end
end
else
is = [];
end
end
Here is an example how to use it:
% Create dummy structure.
a.a = 1;
a.b = '';
a.c = {};
a.d.a.a = 2;
a.d.a.b = 1;
a.d.b = {};
initialisedStruct = StructInit(a);
All the fields are initialised to []. If a field is a structure, that structure's fields will be initialised etc.
