Since the errors / NaNs / inf due to computation errors occur frequently, the need to organize the errors is big.
With that in mind the API version contains some codes for each possible error.
These errors occur mainly due to improper initial values.
101 - Calculated Performance is NaN!
To solve this you need to adjust the input parameters. Try some default values.
102 - Calculated Performance is infinity!
To solve this you need to adjust the input parameters. Try some default values.
103 - Calculated Performance is too big!
When absolute of performance is bigger than 10^7
201 - Calculated x is NaN!
This means that the system is unstable. You need to adjust the theta values close to the defaults. You can also try making smaller the x0,x1 initial values.
202 - Calculated x is infinity!
This means that the system is unstable. You need to adjust the theta values close to the defaults. You can also try making smaller the x0,x1 initial values.
203 - Calculated x is too big to represent!
When absolute of x1 or x2 is bigger than 10^7
