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$\times $N upper left block of an identity matrix of size M$\times $M if M$>$N or N$\times $N otherwise.

W = zeros(M, N);  W is an M$\times $N matrix of zeros.

W = ones(M, N);  W is an M$\times $N matrix of ones.

W = range(f, t $[$, b$]$);  W is a column vector containing values from f to t, spaced by b. The default value of b is one.
