' | ' transposes rows and columns of an array. This operator is equal to the function trans. |
chold |
The function chold is calculating the triangularisation and the Cholesky decomposition of x into matrices b and d, so that b'*d*b = x.
|
det | det computes the determinant of a matrix. |
distance | distance computes the distance between p-dimensional datapoints depending on a specified metric. |
eiggn | eiggn computes the eigenvalues and eigenvectors of a quadratic matrix (or array) in unsorted order. |
eigsm | eigsm computes the eigenvalues and eigenvectors of a symmetric matrix in unsorted order. As usally this functionality extends to higher dimensional arrays. |
inv |
inv computes the inversematrix. As usally this functionality extends to higher dimensional arrays.
|
ludecomp |
ludecomp computes the lu decomposition of a matrix.
|
qr |
computes QR decomposition of a n x p matrix. Column pivoting based on the l_2-norms of the reduced columns may be performed at the users option.
|
qrmat |
returns Q and R matrixes from the output of the QR decompisition
|
qrmat |
returns Q and R matrixes from the output of the QR decompisition
|
svd | computes the singular value decomposition of a n x p matrix x (n >= p). The singular value decomposition finds matrices u, l, v such that x = u*l*v' u, v are orthogonal matrices l is a diagonal matrix |
trans | trans transposes matrices. This function is equal to the operator ' |
