laine | a simple equation solver

Error

[NEWS] 04.10.23 - laine is using a new numerical solver (C++). If you experience any bugs, please report it here (github) or here (google forms)

[UPDATE] 04.10.23 - included functions for Rayleigh flow

laine can solve nonlinear systems of equations in a easy way. Just input your equations and press Solve (F2):

$$\text{In math: }x^2+x=3$$ $$\text{In laine: x^2+x=3}$$

You can also use Functions to input thermodynamic properties in your problem. If you need more details read the README or mail me.
