8/30/2023 0 Comments Determinant of a 4x4 matrix![]() Cofactor of an element: is a number associated with an element in a square matrix, equal to the determinant of the matrix formed by removing the row and column in which the element appears from the given determinant. Determinant of 4x4 Matrix by Expansion Method linear-algebra matrices determinant laplace-expansion 82,429 Solution 1 The pattern +-+- works in the link you gave since they are expanding along the first row it would be the same pattern when expanding along the first column. To evaluate the determinant of a square matrix of order 4 we follow the same procedure as discussed in previous post in evaluating the determinant of a square matrix of order 3. The determinant is A a ( ei fh ) b ( di gf ) + c ( dh eg ). ![]() Her you will learn how to find determinants of matrix 4×4 with example.
