robust-determinant

General purpose robust determinant computation

robust-determinant

Computes the determinant of an nxn matrix as a non-overlapping increasing sequence.

Example

var robustDeterminant = require("robust-determinant")
 
console.log(robustDeterminant([[1,2,3], [4,5,6], [7,8,9]])

Output:

[ 0 ]

Install

npm install robust-determinant

require("robust-determinant")(m)

Exactly computes the determinant of a floating point matrix m

• m is a square matrix

Returns The determinant of m as a non-increasing overlapping sequence

Note For matrices with up to 5 rows, you can avoid an extra dispatch by calling robustDeterminant[n], where n is the number of rows. For example,

robustDeterminant[2]([[1,2],[3,4]]) === robustDeterminant([[1,2],[3,4]])
