Seems possible to do with cells, but I'm still curious, is there any way to do this with arrays, like an array of structures?
Error when appending object to empty array

I am trying to form an array of a particular type of object, specifically the output model from fitdiscr, ClassificationDiscriminant.
Right now I am trying to do the following way:
model_cache = []
for i = 1:10
model = fitdiscr(...)
model_cache = [model_cache; model];
end
But this gives me the error
Undefined function 'throwNoCatError' for input arguments
of type 'double'.
Error in
classreg.learning.internal.DisallowVectorOps/vertcat
(line 49)
function a = vertcat(this,varargin),
throwNoCatError(this); end
Error in main_crossvalidate_sessions (line 84)
model_cache = [model_cache;model];
Which in plain english means I cannot concatenate a double with an object ([] is a double). How do I solve this issue? The way I can think of is ugly - when i = 1, model_cache = [model]; then in subsequent iterations append as usual. Are there simple solutions?
