1 function s=structcut(s,x)
2 % structure=structcut(structure,i)
3 %
4 % I find I often want to shrink a structure
5 % of the form
6 %
7 % s.a(n)
8 % s.b(n)
9 % s.c(n)
10 %
11 % according to some matrix of indices i.
12 % For example it's a pain to do:
13 %
14 % x=s.a>1;
15 % s.a=s.a(x);
16 % s.b=s.b(x);
17 % s.c=s.c(x);
18 %
19 % and if I add another field I have to change
20 % the code in multiple places.
21 %
22 % This function automatically cuts all fields
23 % so the code becomes:
24 %
25 % x=s.a>1;
26 % s=structcut(s,x);
27 %
28 % and continues to work if fields are added.
29 %
30 % Now extended so that fields can be 2D - will try to figure
31 % out which dimension to cut over by looking for the dim which is
32 % equal length for all fields. If all are same cut will occur over
33 % rows.
34
35 % first let's check if it even needs to be cut.
