Details:

In Matlab I often create an empty array and then use a loop to conditionally
add elements to the array concatenation. In Octave this works fine for integer
data types, but fails for structs. For example:


a=5
x=[[], a] %This works

s=struct('name', 'jim')
y=[[], s] %This fails


The error message is:

concatenation operator not implemented for `scalar struct' by `scalar struct'
operations


My feeling is that the second concatenation should work the same as the first
one, and the same as it does in Matlab. If there is a workaround for this
please let me know.

Thanks.
