One of the fundamental operations in machine learning is computing the inverse of a square matrix. But not all matrices have an inverse. The most common way to check if a matrix has an inverse or not ...

THE theory of determinants is in that borderland which separates the “pass” from the “honour” student of pure mathematics. In elementary text-books the subject is rarely more than introduced for the ...

My algorithm for calculating matrix determinants isn't working as it should, so I'm turning to Ars for some maths help.<BR><BR><BR>So...<BR>I'm trying to find the ...

Solution: det (A) = −5, and for n×n matrix adj (A) has determinant (det A)^ (n−1). Here n = 3, so det (B) = (−5)^ (2) = 25.
