Some Basic Matrices

Create basic matrices.

eye(n, m = n)
ones(n, m = n)
zeros(n, m = n)

Arguments

m, n

numeric scalars specifying size of the matrix

Value

Matrix of size n x m. Defaults to a square matrix if m is missing.

No dropping of dimensions; if n = 1, still returns a matrix and not a vector.
