Cody is a MATLAB problem-solving game that challenges you to expand your knowledge. The reverse () method reverses the elements of a given list. In same manner, there is another method flipud() which reverses the order of rows which results in flipping image vertically as shown below. fliplr — NumPy v1. To reverse a row vector, use "r = fliplr(r);". Names, Words or Phrases. You can specify a single dimension size of [] to have the dimension size automatically calculated, such that the number of elements in B matches the number of elements in A. matlab_kmeans, MATLAB codes which illustrate the use of Matlab's kmeans() function for clustering N sets of M-dimensional data into K clusters. I am trying to convert the MATLAB code here to C++. For example, Octave can easily tell you if all the elements of a matrix are finite, or are less than some specified value. CHƯƠNG 1: MATLAB CƠ BẢN §1. Concatenate function can take two or more arrays of the same shape and by default it concatenates row-wise i. B = flipud(A) returns A with its rows flipped in the up-down direction (that is, about a horizontal axis). The x -axis scale ranges from 1 to the number of rows in Y. Microsoft Excel is a powerful program that can help you analyze and visualize your data. If A is a column vector, then flipud(A) returns a vector of the same length with the order of its elements reversed. The following functions that will be used in this lab are:. 비스카이비전의 심교훈입니다.
