Nothing same a= mXn b= pXq then c = [a(1:end),b(1:end)] hope this will help you This depends on size of vector. Consider some vector, lets say with 5 elements, then these are the three function calls: n==5 (user call) n==3 (recursive call) n==1 (recursive call, prints no numbers in even positions) If you remove the semi-colon and print n, you will see that every odd-lengthed vector results in a function call where n==1. MATLAB would make a vector of length 50 with the 50th value being 1. If you want to improve performance and want to create a vector of the proper size. The first and second arguments of these functions are the number of rows and number of columns of the matrix, respectively. The vector is treated as though it is a matrix of the same size as A, so that each element in the vector. It can create vectors, subscript arrays, and specify for iterations. How to Add and Subtract Vectors and Matrices in MATLAB. You can not add vectors of different size. MATLAB : First Order Differential. For an existing vector x, you can assign a new element to the end using direct indexing. For example, create a 2-by-3 matrix and add an additional row and column to it by inserting an element in the (3,4) position. You can add or subtract two vectors. Matlab provides various kinds of tools to create vectors of different types. sr = [1,2,2,2,3,3,3,4,5]; % various possible source ta = [2,3,6,8,6,4,7,6,6]; % various possible targets for i = 1:length (sr) for j = 1:length (ta) nrm_rv1 = random (norm, 0, sqrt (2)); %generate Gaussian (Normal) RV end end But I am not getting how to arrange nrm_rv1 so as to get 9 different Gaussian rv. Two Major Category of Vectors Operation in Matlab. In this example we draw the vectors A and B and display them on the window 0≤x≤10, 0≤y≤10: To display a grid, simply type grid on :.
