det

result = det(A)

Input: A · Output: result

What it is

Determinant of a square Mat or CMat, via LU decomposition.

One call shape — this function is not overloaded.

Code	Input	Output	Description
`result = det(A)`	`A` Mat or CMatnot documented yet	`Num` Complex or CMator `Complex` for a `CMat`	Returns a scalar `Num` (or `Complex` for a `CMat`).

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

A = [4, 7; 2, 6]
print("det(A) = {det(A)}")     # 10

print("rank(A) = {rank(A)}")   # 2

output

det(A) = 10
rank(A) = 2

det(A) — the determinant, via LU decomposition.

From the note above this builtin in the interpreter, where the reasoning was written down as it was built.
