Hmm, it works in my minimal example:
for j=1:5,
data(j).a1=rand(1);
data(j).a2=-rand(2);
data(j).a7=rand(2);
data(j).a11=rand(12);
end
toremove = {'a2';'a7';'a11'};
data2=rmfield(data,toremove);
disp(data2)
I also recreated (tip for next time. Try to create minimal
code, witch cause problem. I don't have your files:)
listremove = []
toremove = {}
for j=1:5,
data(j).a1=rand(1);
data(j).a2=-rand(2);
data(j).a3=-rand(2);
data(j).a4=-rand(2);
data(j).a5=rand(3);
data(j).a7=rand(2);
data(j).a6=-rand(2);
end
stem = 'a';
for L = 1:6
field = [stem,int2str(L)];
if L>2
rmvr = 1
listremove = [listremove L];
end
end
if rmvr == 1
for g = 1:length(listremove)
field = [stem,int2str(listremove(g))]
toremove = [toremove;field]
end
deltaT = rmfield(data, toremove)
end
It works.
BTW, if you always have structures with these same fields,
and you need faster code, listen to TideMan and use stucture
of vectors.

c++, but some information apply to matlab.
