Meshgrid function in matlab

Webmeshgrid and ndgrid create grids using different output formats. Specifically, the first two dimensions of a grid created using one of these functions are swapped when compared to the other grid format. Some MATLAB ® functions use grids in meshgrid format, while others use ndgrid format, so it is common to convert grids between the two formats. Webtorch.meshgrid¶ torch. meshgrid (* tensors, indexing = None) [source] ¶ Creates grids of coordinates specified by the 1D inputs in attr:tensors. This is helpful when you want to visualize data over some range of inputs. See below for a plotting example. Given N N N 1D tensors T 0 … T N − 1 T_0 \ldots T_{N-1} T 0 … T N − 1 as inputs ...

Webmeshgrid (..) builds matrices or 3-D hypermatrices by replicating input vectors along 2 or 3 dimensions. To create arrays of size [ nx, ny] instead of [ny, nx], or with more than 3 dimensions, please use ndgrid (x, y) or ndgrid (x, y, z,..). WebThis function supports both indexing conventions through the indexing keyword argument. Giving the string ‘ij’ returns a meshgrid with matrix indexing, while ‘xy’ returns a meshgrid with Cartesian indexing. In the 2-D case with inputs of length M and N, the outputs are of shape (N, M) for ‘xy’ indexing and (M, N) for ‘ij’ indexing.
