Functions

• diag(v, k = 0)

  returns a copy of the the k-th diagonal if v is a 2-d array 
      or returns a 2-d array with v as the k-th diagonal if v is a
  1-d array.
  

• eye(N, M = None, k = 0, dtype = int_)

  eye returns a N-by-M 2-d array where the k-th diagonal is all ones, and everything else is zeros.

• fliplr(m)

  returns an array m with the rows preserved and columns flipped in the left/right direction. Works on the first two dimensions of m.

• flipud(m)

  returns an array with the columns preserved and rows flipped in the up/down direction. Works on the first dimension of m.

• rot90(m, k = 1)

  returns the array found by rotating m by k*90 degrees in the counterclockwise direction. Works on the first two dimensions of m.

• tri(N, M = None, k = 0, dtype = int_)

  returns a N-by-M array where all the diagonals starting from lower left corner up to the k-th are all ones.

• tril(m, k = 0)

  returns the elements on and below the k-th diagonal of m. k=0 is the main diagonal, k > 0 is above and k < 0 is below the main diagonal.

• triu(m, k = 0)

  returns the elements on and above the k-th diagonal of m. k=0 is the main diagonal, k > 0 is above and k < 0 is below the main diagonal.

• vander(x, N = None)

  X = vander(x,N=None)

  The Vandermonde matrix of vector x. The i-th column of X is the the i-th power of x. N is the maximum power to compute; if N is None it defaults to len(x).
