Matrices
479
Hilbert
Given a positive integer, n, returns the n
th
order Hilbert
matrix. Each element of the matrix is given by the formula
1/(j+k-1) where j is the row number and k is the column
number.
hilbert(n)
Example:
In CAS view, hilbert(4) returns
Isometric
Matrix of an isometry given by its proper elements.
mkisom(vector,sign(1 or -1))
Example:
In CAS view, mkisom([1,2],1) returns
Vandermonde
Returns the Vandermonde matrix. Given a vector [n1, n2
… nj], returns a matrix whose first row is [(n1)
0
, (n1)
1
,
(n1)
2
, …,(n1)
j-1
]. The second row is [(n2)
0
, (n2)
1
, (n2)
2
,
…,(n2)
j-1
], etc.
vandermonde(vector)
Example:
vandermonde([1 3 5]) returns
Basic
Norm
Returns the Frobenius norm of a matrix.
