Hi !
I am looking for a way to create an empty struct with the dimensions 2x1.
So far i only know the comment
StructName = struct
which creates a struct with the dimensions 1x1
Thank you very much in advance!
Marc

A struct with size 2x1 is not empty, it has two elements.
Empty means that at least one dimension has zero size.
The number of fields a structure has is unrelated to its size.
You can easily create a 2x1 (i.e. not empty) structure with no fields:
S = repmat(struct(),2,1)

StructName = struct('FieldName1',cell(2,1),'FieldName2',cell(2,1));
% or
StructName = struct('FieldName1',[],'FieldName2',[]);
StructName = repmat(StructName,2,1);
