## Linear Algebra

'
' 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 square ; matrices or arrays in unsorted order.
eigsm
eigsm computes the eigenvalues and eigenvectors of symmetric ; matrices and arrays in unsorted order.
inv
computes the inverse matrix. The functionality extends to higher dimensional arrays.
ludecomp
computes the LU decomposition of a square matrix, ; where L represents the lower ; and U the upper triangular 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
svd
computes the singular value decomposition of an n x p matrix x (n >= p). The singular value decomposition finds matrices u, l, v such that x = u*l*v', where u and v are orthogonal matrices and l is a diagonal matrix.
trans
trans transposes matrices. This function is equal to the operator '
