WebUsing vectorization, you can write a much more concise MATLAB process. This code shows one way to accomplish the task: x = 1:10000; xsums = cumsum (x); y = xsums (5:5:length (x)); Array Operations Array operators perform the same operation for all elements in the data set. These types of operations are useful for repetitive calculations. WebAug 9, 2010 · A vector is a one-dimensional array of numbers. MATLAB allows creating two types of vectors − Row vectors Column vectors Row Vectors Row vectors are …

WebMay 31, 2016 · Solution 1: Vectorized calculation and direct plot. I assume you meant to draw a continuous line. In that case no for-loop is needed because you can calculate and plot vectors directly in MATLAB. So the following code does probably what you want: x = linspace (0,2*pi,100); y = sin (x); plot (x,y); Note that y is a vector as well as x and that y ... WebCreate a 1-by-2 row vector and a 3-by-1 column vector and raise the row vector to the power of the column vector. a = [2 3]; b = (1:3)'; a.^b ans = 3×2 2 3 4 9 8 27 The result is a 3-by-2 matrix, where each (i,j) element in the matrix is equal to a (j) .^ b (i): a = [ a 1 a 2], b = [ b 1 b 2 b 3], a . florian chauche belfort

WebDec 18, 2024 · I am learning matlab and trying to plot vectors. I defined V= [3;4] to represent 3x^+4y^ and attempt to display using plot (V) hoping to see a vector from origin to (3,4) but instead the graph shows a vector from (1,3) to (2,4). Is it a problem with my plotting settings or am I not using the correct script? Sign in to comment. WebApr 23, 2024 · t = linspace (beginningtime,endingtime,length (y)); plot (t,y) This assumes the y data was sampled at equal time spacings. If that is not the case, you should give more information about how you ended up with two vectors of different lengths and the relationship between t (idx) and y (idx) for a given idx. on 16 Oct 2012 Sign in to comment. WebApr 20, 2024 · In general, the three-dimensional plots consist of the three vectors (x,y,z) in the same graph. In MATLAB, the plot3() function is used to draw the 3D plot graph. You can also use a specified line style, marker, and color for drawing 3D plots. The general syntax to display the 3D plot is, florian chiron
