Hi SymPy Community, I am now trying to understand what happens when I perform WedgeProduct operations on SymPy.
So, I understand how to use the SymPy's Wedge Product to some extent, i.e. I was the one who responded to the question on Stack Overflow: https://stackoverflow.com/questions/76981303/computing-the-wedge-product However, when I have: ''' my_matrix = Matrix([[2, 0, 5], [0, 7, 0]]) r2_r_oneforms = R2_r.base_oneforms() r2_r_vectors = R2_r.base_vectors() cols = [None] * 3 for j in range(3): cols[j] = 0 for i in range(2): cols[j] += my_matrix[i, j] * r2_r_vectors[i] cols_wedge_product = WedgeProduct(*r2_r_oneforms)(*cols) print('cols_wedge_product = ', cols_wedge_product) ''' What I get is: cols_wedge_product = -42 Where does the number -42 come from? On the other hand, if: my_matrix = Matrix([[1, 0, 1], [0, 1, 0]]) I get: cols_wedge_product = 0 What computation leads to 0 here? Can any of you please explain it, e.g. in the terms of the example in the video lecture https://youtu.be/xRf9-hdxB0w?feature=shared&t=2961 ? Thanks so much in advance for your time!
