Parameters
----------
- left, right : matrix
- The two matrices to append to one another.
+ left : matrix
+ The "original" matrix, the one that will wind up on the left.
+
+ right : matrix
+ The matrix to be appended on the right of ``left``.
Returns
-------
Parameters
----------
- top, bottom : matrix
- The two matrices to append to one another.
+ top : matrix
+ The "original" matrix, the one that will wind up on top.
+
+ bottom : matrix
+ The matrix to be appended below ``top``.
Returns
-------
Parameters
----------
- vec1, vec2 : matrix
- The two vectors whose inner product you want.
+ vec1 : matrix
+ The first vector, whose inner product with ``vec2`` you want.
+
+ vec2 : matrix
+ The second vector, whose inner product with ``vec1`` you want.
Returns
-------
Return the spectral norm of a matrix.
The spectral norm of a matrix is its largest singular value, and it
- corresponds to the operator norm induced by the vector ``2``-norm.
+ corresponds to the operator norm induced by the vector Euclidean norm.
