I have 10 .mat files in a folder. The name of each file is mean1.mat, mean2.mat, mean3.mat, and so on. In each mat file I have x and y as variables. I want to plot x and y extracted from each .mat file as a scatter plot. May I know how should I do it?

Thanks in advance.

在 MATLAB Online 中打开

matFiles = dir('*.mat') ; 
N = length(matFiles) ;
figure
hold on
for i = 1:N
      load(matFiles(i).name) ;
      scatter(x,y,[],'b','filled','c')
end
