Hello Community,
I have a little query here (hopefully!) I am simply trying to ask the for loop to run through a struct ('Ss.') with various fields named pl1, pl2, pl3 etc. and work out the standard deviation for each field and assign to a new field named Ss.Sdpl for the same number of fields - 'i'.
for i = 1:N
Ss.Sdpl(i) = std(Ss.pl(i));
end
Unfortunately it returns the error: Reference to non-existent field 'pl', which of course I understand, but how should I write the syntax to run through Ss.pl 1, Ss.pl 2, Ss.pl 3 etc?
Any help would be much appreciated...
10B.

Ss.Sdpl(i) = std(Ss.(sprintf('pl%d', i))) ;

Excellent - many thanks Walter. I completely forgot about having to 'print' the field number. A great help.
