When testing my function to build a structure based on a .dat file, the output shows the desired struct 'kepler' but seems to overwrite with the same size struct 'ans.' Why is it doing this, and how can I fix it?
function kepler = loadkepler(filename)
data = load(filename);
kepler.svid = data(1:end,1);
kepler.meananomaly = data(1:end,2);
kepler.omega = data(1:end,3);
kepler.radius = data(1:end,4);
kepler.inclination = data(1:end,5);
kepler.reftime = data(1:end,6);
end
When I test it with just the 'svid' field, this is the output:
>> loadkepler
kepler =
struct with fields:
svid: [24×1 double]
ans =
struct with fields:
svid: [24×1 double]
Attempts to build a bar graph only work if I use 'ans.svid' instead of 'kepler.svid'

You dont assign the output of the function to a variable - use:
kepler = loadkepler...

Well, that worked!
I thought I wouldn't have to do that, as the struct 'kepler' is created when I assign each field. Does MATLAB not recognize the struct as a valid output of the function? I'm confused as to what's going on behind the scenes.
