When I am writting a rate rule I am getting this above error message. My rule is
LuxI = (1/Tx) ∗ (((tl_luxI ∗ [mRNA_luxI]) ∗ Tx) − ((dLuxI ∗ [LuxI]) ∗ Tx))
I have seen some of the error messages answers of Matlab but nothing worked in my case.Kindly help me with this.

Your ∗ characters are all char(8727), unicode U+2217 https://www.compart.com/en/unicode/U+2217 "Asterisk Operator" .
They instead need to be char(42), unicode U+002A https://www.compart.com/en/unicode/U+002A "Asterisk"

Actually, sir, I want some help regarding the same. Sir, I am referring to a paper in which they have build a model in Simbiology but they have not given the concentrations and units for all the parameters. So for now I have set the units by myself. So I am getting an error that the "Quantities of different dimensions cannot be added or subtracted". I know that this error is due to the random units(dimensions) that I have set. But can you help me or guide me on how can I remove this kind of error. I have tried unit conversion to true but is not working. Probably I have misunderstood the meaning of unit conversion.

Unit conversion is for converting between compatible units, such as mm and m, or Newton-metres and Joules.
It does not assign "whatever units that make the calculations work out".
