Finding the determinant of the 3 x 3 matrix with keyword alphabet. < k துணைக்காரணி. j s {\displaystyle (-1)^{\sum _{s=1}^{k}i_{s}-\sum _{s=1}^{k}j_{s}}} In this article, we use the inclusive definition of choosing the elements from rows of I and columns of J. Examples of question hooks for essays. i Cofactor definition is - the signed minor of an element of a square matrix or of a determinant with the sign positive if the sum of the column number and row number of the element is even and with the sign negative if it is odd. ≤ {\displaystyle M_{I,J}} To compute the determinant of any matrix we have to expand it using Laplace expansion, named after French… J i I ) The cofactor matrix of a square matrix A is the matrix of cofactors of A. k ) Sometimes the term is used to refer to the k × k matrix obtained from A as above (by deleting m−k rows and n−k columns), but this matrix should be referred to as a (square) submatrix of A, leaving the term "minor" to refer to the determinant of this matrix. / edit ; Tamil Technical Terminologies adjoint of the matrix of order n. aij. ) ( i+j ) M ij ) is called the adjoint matrix. 2...
