MATRIXADJOINT (a)


  • is any set of values.

Description

  • This function shows the Adjoint of a given matrix.
  • In , is the set of matrix values.
  • Adjoint of a matrix is called adjugate, classical adjoint, or adjunct.
  • Adjoint of a matrix formed by taking the transpose of the cofactor matrix of a given original Square matrix.
  • Adjoint of matrix A is written by .
  • The adjugate of A is the transpose of the cofactor matrix C of A, .
  • Also adjoint of a matrix is defined by .
  • The adjugate of 1x1 matrix is .
  • The adjugate of 2x2 matrix is .
  • Consider3x3 matrix .
  • Its adjugate is the transpose of its cofactor matrix:
