There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level,...
forii=1:numel(MyStruct) ifisempty(MyStruct(ii).FieldName) ind=[ind, ii]; end end Thenindcontains all the indexes where the structure field is empty. For instance if you then want to remove them from the structure: MyStruct_init=MyStruct; ...

If the variable already exists, then MATLAB replaces the original content with new content and allocates new storage space, where necessary.For example,Total = 42 The above statement creates a 1-by-1 matrix named 'Total' and stores the value 42 in it....
If numeric, whether the variable is real or complex If sparse, its indices and nonzero maximum elements If a structure or an object, the number of fields and field names To access themxArraystructure, use functions in the C or Fortran Matrix APIs. These functions allow you to create, read...

Than I would check if [ ] exists in that line, e.g. with strfind. If so, remove the [ ] and create a new struct field with this name, e.g. use the eval command. If the line doesn't include [ ] than you have to assign this variable to the field. 3 Comments Show 1 older ...
