Entscheidungsmodelle zur InvestitionsplanungMatrices are arrays of numbers. The arrays have a dimension of . × .. The present discussion is limited to two cases: square arrays (. x .) that are called matrices, and vectors (1 × .). The matrices have elements .. where the indices i (1 ≤ . ≤ n) denote the rows while; (1 ≤ . ≤ .) denote the columns.

Entscheidungsmodelle zur InvestitionsplanungA group is a collection of elements that obey certain multiplication properties. Here the word “multiplication” has a general meaning: it could entail multiplication of matrices, the adding of numbers, or the rotation of a figure.

https://doi.org/10.1007/978-3-322-87439-9Some differential equations are solved in one dimension. The first is Laplace’s equation. Its only Solution is Ø(.) =. + . where the constants .,. are set by the boundary conditions. A second order equation always has two constants. The Solution is dull: it is a straight line.

Determinants,A determinant is a single number obtained by a particular evaluation of an . x . matrix of values. The number is real if the elements of the matrix are real, but could be complex if the elements are complex. Below are given some techniques for evaluating the determinant ofa . × . matrix.
