(quote ^,Matrix,List)

f^{i,j,k,...} -- produce the submatrix of a matrix f consisting of rows numbered i, j, k, ... .

Repetitions of the indices are allowed.

If the list of row indices is a permutation of 0 .. n-1, where n is the number of rows, then the result is the corresponding permutation of the rows of f.
