Hello,
lately I've been using cell arrays to hold structs. Since the structs are uniform (all of them have the same fields), I thought of shifting to struct arrays and be able to traverse the structures and get an array with a value corresponding to each structure by using the . indexing operator.
Here s0 is the struct array. Each struct in s0 has a member called m
The resulting type of object is of type cs-list. Now I want to make a plot of
s0.m against, say, s0.v
the plot function shows no error but the resulting plot has no lines, just a lengend for 3 lines.
Matlab documentation says you should use a for loop to convert between a cell array (which i can obtain with {
s0.m}).
I was wondering if there is any way in octave to do this in a more direct fashion.
I don't even know if the problem is well posed, but it would make the whole concept of struct arrays much more useful. I believe the main advantage of struct arrays is being able to index them as if they were structs and get "something", a cs-list. If a cs-list is made out of simple scalars, it should be trivial to convert it to a matrix.
If {s0.m} gives me a cell array, then [s0.m] should give an array.
I guess I could try to implement this myself on octave, but I don't know if there's a point, maybe a solution already exists and I'm too ignorant :-)
Any ideas?
