Plotting displacement field vector using quiver

I have two displacement arrays x and y. How to plot displacement field using quiver option. Following is the code which I have used. I am not sure whether the code is correct.

x1=load('DISP_X.xvg'); y1=load('DISP_Y.xvg'); [X,Y]=meshgrid(x1,y1); quiver(X,Y)

Please help me. Thanks in advance.

Hi,

To plot a displacement field using the “quiver” function in MATLAB, you need to ensure that your displacement arrays ‘x1’ and ‘y1’ are correctly structured. The “quiver” function requires two sets of data: the grid points where vectors are anchored, and the vector components in the x and y directions.

Assuming the data in your ‘. xvg’ files is correctly formatted and corresponds to the expected dimensions when loaded into MATLAB, Use “meshgrid” to create a grid where the vectors will be anchored.

% Assuming x1 and y1 are vectors. If they are matrices, skip meshgrid
[X, Y] = meshgrid(1:size(x1, 2), 1:size(y1, 1));

Now, Use the “quiver” function to plot the vectors.

% Plot the displacement field
quiver(X, Y, x1, y1);

I hope the solution provided above is helpful.
