I'm trying to run this model with SimBiology but see an error message.
BIOMD0000000268_url.xml
SBML L2V4 representation of Reed2008_Glutathione_Metabolism
"piecewise" is a function in matlab but it seems SimBiology model bulider recognizes it as a variable... Any idea?
---------
RULE
Aminoacid_input = piecewise(breakfast,and(le(7,daytime),le(daytime,10)),lunch,and(le(12,daytime),le(daytime,15)),dinner,and(le(18,daytime),le(daytime,21)),fasting)
error message: "Rule include varaibles that are unidentified." with red higllight for "piecewise"

the piecewise.m file will need to be either in the Current folder or anywhere on your MATLAB Path for SimBiology to use it.
Please note that there is a piecewise function in the Symbolic Math Toolbox but it only supports symbolic variables and will not work in this case.
In case you need a definition of the piecewise function, you could use the one attached.
Best,
