# PyTorch torch.trapezoid Function * * Pytorch torch Reference Manual](#) `torch.trapezoid` is a function in PyTorch used to compute the trapezoidal integral. This function uses the trapezoidal rule to perform numerical integration of a given function. ### Function Definition torch.trapezoid(y, x, dx) ### Parameter Description * `y`: Function values to integrate * `x`: Values of the integration variable (optional) * `dx`: Sampling spacing (used when x is not provided) * * * ## Usage Examples ## Example import torch # Use dx for trapezoidal integration y = torch.tensor([1.0,2.0,3.0,4.0]) # dx=1.0 indicates uniform sampling spacing result = torch.trapezoid(y, dx=1.0) print("Trapezoidal integration result:", result) # Use x coordinates for integration x = torch.tensor([0.0,0.5,1.0,1.5]) y2 = torch.tensor([0.0,0.5,1.0,1.5]) result2 = torch.trapezoid(y2, x) print("Integration result using x coordinates:", result2) Output result: Trapezoidal integration result: tensor(7.5000) Integration result using x coordinates: tensor(1.2500) * * Pytorch torch Reference Manual](#)
