I am trying to estimate a parameter using the change in drug concentraiton (Concentraiton), m, b. I use the the following rule:
Rule_6 = exp(m*log(Concentraiton)+b)
When I run the equation, I get the following error:
Cannot perform dimensional analysis for rule 'rule_6' because of the function 'exp' in the rule. Because UnitConversion is on, correct simulation results will depend on this expression being dimensionally correct. Additionally, SimBiology simulates the model in a unit system determined at runtime. The units are determined by the units used in the model and the model's configset. Unless the inputs and outputs to the function are dimensionless, results may change due to configset option changes, changes to the model, or version changes in SimBiology. It is recommended that input and output arguments to functions be dimensionless to ensure correct results.
Variables m and b are dimensionless as is the parameter I am estimating. I divided Concentraiton by Concentraiton0, both as mg/L, to get a dimensionless value. Do you have any advice for estimating the variable while still keeping the UnitConversion on?
