Also, create an empty vector called prime_numbers; In the while loop, prompt the user for an integer input and determine whether it is a prime number or not; Update the vector prime_numbers accordingly; Also, prompt the user to continue or terminate the session and update the continue_flag variable accordingly 1 Link Answered: Walter Roberson on 14 Oct 2019 I used A = ClassName.empty (sz1,.,szN) or A = ClassName.empty (sizeVector) syntax : a=ClassName.empty (2,2) but I got this error: Undefined variable "ClassName" or class "ClassName.empty". dimensions of length 1. This section lists property names along with the type of . Concatenate 2D Numpy array axis column wiseFor working with numpy we need to first import it into python code base. You can also create a matrix r by appending these two vectors, the vector r2, will be the second row of the matrix . In fact, this is one of MATLAB's main advantages. 7 Answers Sorted by: 80 Using repmat is by far the most efficient way to preallocate structs : N = 10000; b = repmat (struct ('x',1), N, 1 ); This is ~10x faster using Matlab 2011a than preallocating via indexing, as in N = 10000; b (N).x = 1 The indexing method is only marginally faster than not preallocating. 2 Comments Steven Lord on 18 May 2020 You can also specify p as a codistributed or distributed array. You can override the empty method in class definitions. An alternative would be to use NaT ('not a time'), which is of type datetime and is more obviously a default value. sites are not optimized for visits from your location.
