I want to intragate the equation dx/dt=-xD + ux (x=biomass D=dillution rate u=growthrate ),and u is replaced by umax*I/(I+km).
But every time I try, I get an error. I tried the “int" and the quad but nothing works.
The image of the code and the error are attached.
Please tell me what is wrong. It would mean a lot to me.
(p.s I use octave 4.4.1 app and I don’t have any packages installed due to program setting issues)
Best regards.
