WebAlgorithms. When concatenating an empty array to a nonempty array, cat omits the empty array in the output. For example, cat(2,[1 2],[]) returns the row vector [1 2]. If all input arguments are empty and have compatible sizes, then cat returns an empty array whose size is equal to the output size as when the inputs are nonempty. For example, … WebI have 100 2D lists a0 to a99, it is easy to convert them into arrays (I verified already): print(np.array(a0).shape) # (2,150) print(np.array(a1).shape) # (5,150) print(np.array(a2).shape) # (10, 150) # the sizes of a0 to a99 vary from (1,150) to (10, 150) only I want to combine these 100 3D arrays into ONE 3D array, for example … crucial word form WebSep 25, 2024 · Combining a one and a two-dimensional NumPy Array.
