 [Numpy-discussion] Numpy capabilities? From: Nancy Keuss - 2004-01-25 18:33:29 ```Hi, I will be working a lot with matrices, and I am wondering a few things before I get started with NumPy: 1) Is there a function that performs matrix multiplication? 2) Is there a function that takes a tensor product, or Kronecker product, of two matrices? 3) Is it possible to concatenate two matrices together? 4) Is there a way to insert a matrix into a subsection of an already existing matrix. For instance, to insert a 2x2 matrix into the upper left hand corner of a 4x4 matrix? Thank you very much in advance! Nancy ```
