By applying a linear transformation matrix, the resulting matrix can be decomposed into two sets of vectors: row vector column vector The matrix definition of the vector matrix is: In this paragraph, all vectors in a matrix are represented by their rows. MATLAB allows creating two types of vectors Row vectors Column vectors Row Vectors Row vectors are created by enclosing the set of elements in square brackets, using space or comma to delimit the elements. 1 Answer Sorted by: 3 Using the transpose function .' or the colon operator (:) Do not include these two lines of code, they are just set-up for this example: A = ones (1, 60); % create an arbitrary row vector 1x60 B = ones (60, 1); % create an arbitrary column vector 60x1 Choose one of these options, a comment above each describes what it does. You may receive emails, depending on your. Duplicate the first row and the first column of a matrix. The question is a bit convoluted. Sign in to comment. STEP1: Open MATLAB. Code: a = [1; 3; 5]' Output: The output that we will get will be a single row with elements 1, 3, 5. 2. The colon is one of the most useful operators in MATLAB . Users are just too lazy to search SO, or read the basic documentation @searcoding the question you linked refers to flattening a matrix, although the answers involve transposing I wouldn't call the questions duplicates. Create a column vector x with elements x 1 = 1, x 2 = -2 and x 3 = 5. multiple outputs in a comma-separated list. In linear algebra, a column vector with elements is an matrix [1] consisting of a single column of entries, for example, . results. By using ismember: [~,i2] = ismember(a,b) the index. In the latter case, read the answer. How to extract and convert a column to a row vector so say I want to extract 5;10;9;25 how do I convert that to a row when I extract it?
