WebDec 16, 2024 · In Python, the cross product is also known as vector product and it is denoted by symbol X. This method is available in the NumPy package module and it is also used for linear algebra and matrices. This method will always return the cross product of two given matrices and it is defined as the axis of C containing the cross product. Syntax: WebI would like a "cross product"-esque function that will take each value from the first vector and raise it to the exponent of each value in a second vector, returning a matrix. Is there anything built in to numpy that does this? It could be done with loops but I'm looking for something efficient. For example:
