Rand x.size
WebbReturns a new tensor with a dimension of size one inserted at the specified position. The returned tensor shares the same underlying data with this tensor. A dim value within the range [-input.dim () - 1, input.dim () + 1) can be used. Negative dim will correspond to unsqueeze () applied at dim = dim + input.dim () + 1. Parameters: WebbX = randn (size (A)); Size and Data Type Defined by Existing Array Create a 2-by-2 matrix of single-precision random numbers. p = single ( [3 2; -2 1]); Create an array of random numbers that is the same size and data type as p.

Webb14 sep. 2024 · y = rand ( [1 100]); voronoi (x,y) What I am now trying to achieve is to pick a line across the bulk of the image and have this line made of say around 1000 pixels. Each pair of pixels will be separated by some distance 'r'. Then I would then like to know how many pixels belong to each grain. (Different grains will have different pixel values.)
