### B.6 Special matrices

The following statements are used to construct some special matrices, like the identity or a matrix of zeros.

 Syntax Arguments and performed function W = eye(M, N); W is the M$×$N upper left block of an identity matrix of size M$×$M if M$>$N or N$×$N otherwise. M must be a positive integer N must be a positive integer W = zeros(M, N); W is an M$×$N matrix of zeros. M must be a positive integer N must be a positive integer W = ones(M, N); W is an M$×$N matrix of ones. M must be a positive integer N must be a positive integer W = range(f, t $\left[$, b$\right]$); W is a column vector containing values from f to t, spaced by b. The default value of b is one. f must be a scalar t must be a scalar b must be a scalar
