An overview

In Macaulay 2, each matrix is defined over a ring, (see rings). Matrices are perhaps the most common data type in Macaulay 2.
  • making matrices
  • input a matrix
  • random and generic matrices
  • concatenating matrices

  • operations involving matrices
  • simple information about a matrix
  • basic arithmetic of matrices
  • kernel, cokernel and image of a matrix
  • differentiation

  • determinants and related computations
  • rank of a matrix
  • determinants and minors
  • Pfaffians
  • exterior power of a matrix

  • display of matrices and saving matrices to a file
  • format and display of matrices in Macaulay 2
  • importing and exporting matrices

    • For an overview of matrices as homomorphisms between modules, see modules I. For additional common operations and a comprehensive list of all routines in Macaulay 2 which return or use matrices, see Matrix.
