circulant#
- scipy.linalg.circulant(c)[source]#
- Construct a circulant matrix. - Parameters:
- c(…, N,) array_like
- The first column(s) of the matrix. Multidimensional arrays are treated as a batch: each slice along the last axis is the first column of an output matrix. 
 
- Returns:
- A(…, N, N) ndarray
- A circulant matrix whose first column is given by c. For batch input, each slice of shape - (N, N)along the last two dimensions of the output corresponds with a slice of shape- (N,)along the last dimension of the input.

 - Notes - Added in version 0.8.0. - Examples - >>> from scipy.linalg import circulant >>> circulant([1, 2, 3]) array([[1, 3, 2], [2, 1, 3], [3, 2, 1]]) - >>> circulant([[1, 2, 3], [4, 5, 6]]) array([[[1, 3, 2], [2, 1, 3], [3, 2, 1]], [[4, 6, 5], [5, 4, 6], [6, 5, 4]]])
