Import SBML file with function definitions into SimBiology

Functions to import SBML files containing function definitions into SimBiology.

You are now following this Submission

These functions allow you to import SBML files containing function definitions into SimBiology.
Two methods are available:
- sbmlimportFunExternal
This function saves each function definition as separated MATLAB function in the current directory.
The resulting SimBiology model supports the 'Model acceleration' mode.
Function definitions containing the MathML function 'piecewise' are also supported.
In that case, to ensure that the ODE solver registers the transitions events are added to the SimBiology model.
- sbmlimportFunReplace
This function replaces all function calls in the reaction rates by the associated expressions.
The resulting SimBiology model supports the 'Model acceleration' mode.
It does not support the use of the MathML function 'piecewise' in the function definitions.
Usage:
sbmlimportFunExternal()
sbmlimportFunExternal(filename)
sbmlimportFunReplace()
sbmlimportFunReplace(filename)

Updated license

1.1.0.0

-Both methods:
* better warning handling
* replace math and logical operators in SBML functions and event triggers

- sbmlimportFunExternal:
* add events for 'piecewise' calls only if trigger contains non-constant parameters, species or volumes.

1.0.0.0

- Updated function headers.
- sbmlimportFunExternal: Piecewise function defined in a separated MATLAB file instead of a subfunction.
