🧠 Update log

🧠 [2.0.0] 2025 May 9

To further improve physical consistency,

I replaced heat transfer module by set of energy balance equations,

Start from version 2.0.0

🧠 [2.0.1] 2025 May 10

Add another parameter: "envelop_mdl",

Allow user to use the new physics based module or previous data driven module.

🧠 [2.0.2] 2025 May 10

Fix bug due to parameter: "envelop_mdl",

Vectorize calculation,speed improved by ~6 times.

🧠 [3.0.0] 2025 June 11

Update datadriven modnn RC based envelop_mdl really hard to tune on new dataset

🧠 [3.0.1] 2025 June 11

Add a step function for one step ahead prediction

🧠 [3.0.2] 2025 June 11

Fix bug for step function

🧠 [3.0.3] 2025 June 11

Fix bug for step function

🧠 [3.0.4] 2025 Sept 10

Didn't work on it for 3 months, just update the latest version Will use it for BESTOpt building dynamic model

🧠 [3.0.5] 2025 Sept 15

3.0.4 CAN-NOT work at all, I mistakenly comment one line and add a new line of code

🧠 [3.0.6] 2025 Sept 15

Fix temperature unit conversion issue
