Hi. I'm very ew with MATLAB and currently using it for my research. Currently I'm able to get raw data of piezoeletric signals using handyscope and filter it. I'm trying to plot an animation (e.g: a colormap/meshgrid) of the propogation of the wave signals on a 5x5 grid points generated at a fixed time lapse.

The problem is I don't know how to assign each of my data collected for each point to a 5x5 grid in the MATLAB and how to compile it and make it into an animation.

Some sort of example I'm trying to get is as below:

or

Both of the examples above i presumed to come with an equation for the data acquired. I am currently stuck with raw vector datas to be plotted. Some of the idea I'm able to come up with is collecting all the data from each point into a single matrix and assign it onto each grid point. But I don't know how. Any ideas?

在 MATLAB Online 中打开

you can use drawnow and pause(0.1) in a loop.

For example:

x = 1:20;
y = 1:20;
[X, Y] = meshgrid(x,y);
for j = 1:10
    surf(X,Y,rand(20));
    axis([1 20 1 20 0 1]);
    drawnow;
    pause(0.1);
end

sorry. the row 1-5 is my data imported into matlab. and i'm iterating the data for each row one by one in a for loop to make a wave animation based on the different value of data at different time.
