MATLAB: Output of sbiosteadystate task

SimBiology

I'm using

[success, variant_out] = sbiosteadystate(modelObj)

to find the steady states of the non-constant species in my model. However, variant_out returns the values of all species(consatnt and non-constant), constant parameters and constant compartments. How do I get variant_out to return only the steady state values of non-constant species?

Thanks a lot

What you get is not a function handle but an heterogenous array of SimBiology objects. This array contains a mix of different component types like species, parameters or potentially compartments.

If this is what you want, you can get their names with

names = get(VariableSpecies, 'Name')

But if you only wanted species (not parameters nor compartments), you can get them like this:

speciesObj = sbioselect(modelObj, 'Type', 'Species','Where','Constant','==',false)
names = get(speciesObj, 'Name')

MATLAB: How to use the ‘exist’ function for a SimBiology built-in function

Hi Ciaran,

The list of built-in and user-defined kinetic laws are stored on something called the SimBiology root object. You can access is with the sbioroot function. For example, here is sample code to get lists of the kinetic laws:

root = sbioroot;
userDefinedLaws = root.UserDefinedLibrary.KineticLaws;
builtinLaws = root.BuiltinLibrary.KineticLaws;

Alternatively, if you want to search for a kinetic law with a particular name, you can use the sbioselect. For example, here's how you could use sbioselect to find the MassAction kinetic law:

lawList = sbioselect('Name', 'MassAction', 'Type', 'abstract_kinetic_law')

If the output from calling sbioselect is empty, then the kinetic law with the specified name has not been added to the library. If you leave out the 'Type', 'abstract_kinetic_law' part of the command, you'll find all SimBiology objects with the specified name. You can read more about sbioselect here. And here is a list of all the Type values used in SimBiology, in case you ever want to search through the names of other types of objects.
