# PyTorch torch.vdot Function * * (#) `torch.vdot` is a function in PyTorch used to compute the dot product of two vectors (also known as vector dot product). Unlike `torch.dot`, `torch.vdot` can handle complex vectors and automatically multiplies each element of the first vector with the conjugate element of the second vector. ### Function Definition torch.vdot(input, other) * * * ## Usage Examples ## Example import torch # Real number vectors a = torch.tensor([1,2,3]) b = torch.tensor([4,5,6]) result = torch.vdot(a, b) print("vdot result:", result) # 1*4 + 2*5 + 3*6 = 32 # Complex vectors c = torch.tensor([1+2j,3+4j]) d = torch.tensor([5+6j,7+8j]) result_complex = torch.vdot(c, d) print("Complex vdot result:", result_complex) Output: vdot result: tensor(32)Complex vdot result: tensor(70.-6.j) * * (#)
