Let’s create some discrete plots using Matlab function 'stem'. For our purposes, we are going to define the function as 1 when the argument of the Dirac function is 0, and the output will be 0 for any other value of the input argument.
* Challenge: Plot functions x (blue squares and line), x^2 (red circles and line) and x^1/2 (green diamonds and line) between (0,2) on the same plot. Let s do Exercise 1! Creating scripts and functions using m-files % Matlab scripts are files with ".m" extension containing Matlab % commands. Variables in a script file are global and will change the
In the code we first create a vector for x and evaluate the three functions we wish to plot. Next we create a figure window with figure function and immediately after we use the command hold on - this tells MATLAB to put all of the plots from this point forward into the current figure window.
Matlab is an interpreted language and looping through a vector like this is the slowest possible way to change a vector. The notation used in the first statement is much faster than the loop. A better example, is one in which we want to perform operations on the rows of a matrix.
Matlab Matlab is a tool for doing numerical computations with matrices and vectors. It can also display information graphically. The best way to learn what Matlab can do is to work through some examples at the computer.
Hello Everybody I have 4 vectors x,z,dx,dz which respectively are coordinate of x,coordinate of z, displacement in x direction ,displacement in z direction. I want to plot a vector field graph for displacement, to see the amount and direction of displacement on each point.size of each vector is (110000,1).
As with most MATLAB functions there's a lot of things we can do with mesh grid, but we're just going to create a square grid for now, cause that's really simple. So we'll pass it a vector, to ...

The basic plot command Two-dimensional line and symbol plots are created with the plot command. In its simplest form plot takes two arguments >> plot(xdata,ydata) where xdata and ydata are vectors containing the data.
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 created by enclosing the set of elements in square brackets, using space or comma to delimit the elements. f = feather(___) returns a vector of Line objects with length(U)+1 elements. The first length(U) elements represent individual arrows, and the last element represents a horizontal line along the x-axis. Use these Line objects to control the appearance of the plot after creating it.

Oct 28, 2014 · Could you give an describtion of how the arrow coordinates are set exactly? x and y need to be between 0 and 1 within annotation, so if I want the arrow to go from e.g. (x1,y1) = (3,0.5) and (x2,y2) = (6,0.5) how is x and y adjusted for exact location? I am trying to plot a singular vector in MATLAB using arrow function, but MATLAB keeps giving me the error: Undefined function 'arrow' for input arguments of type 'double' How do I fix this? Here is the MATLAB code: function Plot_Singular_Vecor() A=[1 1;2 3]; [U,S,V] = svd(A); % Find singular value decomposition.

Dear MATLAB users I am plotting velocity vectors in MATLAB using quiver command. I would like to display velocity vector scale on the plot, i.e. to show an arrow and to specify that this arrow is for example 2cm/s. I do not know how to do it and would be grateful if someone can let me know how to do this. Thank you very much in advance. Best ...
Syntax Examples. The Octave syntax is largely compatible with Matlab. The Octave interpreter can be run in GUI mode, as a console, or invoked as part of a shell script.More Octave examples can be found in the Octave wiki. Plotting Random Vector Field with quiver I have a matrix C which contains random complex numbers. I want to plot my vector field, need help using quiver function.
In this example, the plot command specifies a solid, red line ('-r') for the cosine function and a dash-dot, blue line ('-.b') for the sine function. See Also. LineSpec, plot. Adding a Legend to a Graph for more information on using legends. Annotating Plots for related functions

Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome.
The way MATLAB plots a curve is to plot a sequence of dots connected by line segments. The input for such a plot consists of two vectors (lists of numbers). The first argument is the vector of x-coordinates and the second is the vector of y-coordinates. MATLAB connects dots whose coordinates appear in consecutive positions in the input vectors. In this example, the plot command specifies a solid, red line ('-r') for the cosine function and a dash-dot, blue line ('-.b') for the sine function. See Also. LineSpec, plot.
