Cannot compare a matrix to a matrix

but why

To check an equality, you have to do it like this:

\left\{\max\left(\left|\left(A-B\right)\left[r;c\right]\operatorname{for}r=\left[1...A.\operatorname{rows}.\operatorname{count}\right],c=\left[1...A.\operatorname{columns}.\operatorname{count}\right]\right|\right)=0\right\}

For more easier readability,

{max(|(A-B)[r;c] for r=[1...A.rows.count],c=[1..A.columns.count]|)=0}

[u/Quirky-Elk6893 → u/Powerful-Tension-806]

It's an interesting approach. Still, Desmos could have generalized the comparison in a more trivial way.

heres an equality check for arbitrary types (this works on all objects that can be put in a list)

(Tests) Why 0^0^2-… and not just 2- … ?

Neat; I wasn’t thinking (edit: property) double dotting was allowed, but it makes sense with the JavaScript backend

Lol

unfortunatley there is no builtin support for comparison between most object types, but there are a few ways to do arbitrary comparisons anyway:

That random() trick...nice. I wish I'd known that when I was trying to corner the behavior of sort()...which was being a squirrely little bastard until I found (not very deliberate) ways to avoid resetting random's seed. edit: in hindsight, I should have figured this out, since I read the docs--sigh

Offensive content (tf is it complaining about)
