Organizatorium

  • Scalar
  • Matrix - two-dimensional array (rows, columns)
  • Vector - a matrix with just one column.
  • 1-indexed and 0-indexed vectors.
  • Linear map.
  • Vector space.
  • Point in a multi-dimensional vector space, equivalent with a vector in the same multidimensional vector space.
