| Description |
This function is useful if numeric values from a structure array are to be extracted using the notion M = S.field] UNEMPTY makes sure that empty matrices in the structure do not affect the size of M.
S = unempty(C) sets all occurences of empty matrices in all fields of C to NaN.
[S,nc] = unempty(C) reports the number of changed fields in nc.
S=unempty(C,F) sets in a structure array all occurences of empty matrices for field F to NaN.
S=unempty(C,F,value) sets all occurences of empty fields to value.
Example:
S=[struct('f',1) struct('f',2) struct('f',[]) ];
disp([S.f]) % size is different from S
1 2
S = unempty(S);
disp([S.f]) % size is the same as S
1 2 NaN |
