Folks,

I'm trying to port some Matlab code that loads a file of structs and
then returns some of the structs to the calling function.  Loading the
file works fine from the command prompt, but when I call the function
to load the file it returns empty variables. Examples below, not sure
what to do next. Thoughts?

I'm using GNU Octave, version 2.1.33 (i386-redhat-linux-gnu).


`The function does the following

function [const,sat,shallow]=t_getconsts;
if exist('t_constituents.mat');
  load -force "t_constituents.mat" %has structs inside
else
% do some math to generate the file
end;


`The file can be loaded fine but the variables are lost when I leave
`the scope.
`Global scope from the prompt


>> load -force t_constituents.mat
>> whos

*** local user variables:

prot  type                       rows   cols  name
====  ====                       ====   ====  ====
 rwd  struct                        -      -  const
 rwd  scalar                        1      1  prefer_zero_one_indexing
 rwd  struct                        -      -  sat
 rwd  struct                        -      -  shallow


`but the function won't return anything

>> [const,sat,shallow]=t_getconsts
const = []
sat = []
shallow = []
