Dear Mathieu,
thanks for your reply.
I tried the synthax you suggest and the output is always empty. Below a
simple code to verify it.
I know that it is very simple to build a customized grep-like function
but my real 3-dimensional struct array is quite large and I'm worried
about computational time.
Here is a not-working sample code:
-----------------------
-->N=10;for i=1:N; for j =1:N; for k=1:N; slot(i,j,k).cdl="";
slot(i,j,k).modulo=""; end; end; end
-->slot
slot =
10x10x10 struct array with fields:
cdl
modulo
-->slot(1,2,3).cdl="abc";
-->find(slot.cdl=="abc")
ans =
[]
----------------------
Best,
g.
