Is it possible for me to calculate a multiplication between two vectors with non numerical elements-CodePudding

Recently I have been using numpy's .cross function to multiply vectors. However, the function doesn't support non-numerical elements for the arrays, i.e a=[5t,6,0]. I was wondering if it was possible to, in Python, calculate such operations with maybe another function, or another method. Any suggestions?

CodePudding user response：

You can do it with SymPy module of Python.

import sympy
t = sympy.symbols('t')
a = sympy.Matrix([5*t,6,0])
b = sympy.Matrix([8*t**2, 3, 5])
print(a.cross(b))

Output:

Matrix([
[             30],
[          -25*t],
[-48*t**2   15*t]])
