What is new in Algosim 3.1?

September 2022

Major changes

The main new feature in Algosim 3.1 is 3D visualisation.

On the same topic of multivariable calculus, a custom function in several variables can now be passed a single list or vector of values instead of the individual arguments one by one.

Language changes

A function in several variables can now take its arguments as a single list or vector.

For instance,

F ≔ (u, v) ↦ u^2 + 4⋅u⋅v − 3⋅v^2;
P ≔ ❨1, 2❩;
F(P)

−3

This can also be written

F(1, 2)

−3

and previously this was the only way to evaluate F.
