MATLAB: Accessing a simbiology class

classindexingmodel objectSimBiology

Hi to all,
I would like to access the content of the class output by the command,
 msp = get(modelobj,'species')
where "modelobj" is a simbiology model object. "msp" prints as an array but I have tried several indexing conventions and none of them results in the elements of the array. This kind of array is common in simbiology and I just don't find how to access it.
Thanks in advance,
Omar

Hi Omar,
In the code you typed above, "msp" should be a vector of species objects that you can index using "msp(1)", "msp(2)", etc. Here is an example using a demo model included with SimBiology:
>> m1 = sbmlimport('lotka.xml')
     SimBiology Model - lotka 
     Model Components:
       Compartments:      1
       Events:            0
       Parameters:        3
       Reactions:         3
       Rules:             0
       Species:           4
>> s = m1.Species; % equivalent to get(m1, 'Species')
>> s(1)
     SimBiology Species Array
     Index:    Compartment:    Name:    InitialAmount:    InitialAmountUnits:
     1         unnamed         x        1                 
>> s(end)
     SimBiology Species Array
     Index:    Compartment:    Name:    InitialAmount:    InitialAmountUnits:
     1         unnamed         z        0
