covariance clj

(covariance m)

Calculates the covariance matrix of a 2-D matrix

create-identity-matrix clj

Finds the cross product of two (indexed) rows of a matrix

determinant clj

(determinant m)

Caluclates the determinant of a square matrix by first calculating it's uper triangular matrix and then multiplying it's diagonal elements together while taking into account the number of row swaps made in the process

dimension clj
