i have 40 list of people data

each data is having 2 data of age

i have used image below to explain it clearly

so from age data a1 4 graphs and a2 4 graphs

from 1 data i am getting 8 graphs..

i am facing difficulty to save graphs numbered as figure1,figure2 in a folder

a=dlmread('S11.txt')

freq=a(:,1)

Spam=a(:,2)

Spam=reshape(Spam,[1,21])

x = freq;

y = spam;

plot(x,y);

grid on

title('plot');

xlabel('freq');

ylabel('sparm');

is there any command which will find out no of figures already generated and then based on that save the figures

like this i have to plot for multiple sparameters ..how to save it as figure1 figure2 .figure 3 in jpg format in folder

在 MATLAB Online 中打开

files = dir('*.txt');
files = fullfile({files.folder},{files.name});
for ii = 1:numel(files)
    
    a=readmatrix(files{ii});
    
    f = figure();
    plot(a(:,1),a(:,2));
    grid on
    title('plot');
    xlabel('freq');
    ylabel('sparameter');
    saveas(f,sprintf('figure%d.jpg',ii));
    delete(f);
    
end
dir('*.jpg')
figure1.jpg  figure2.jpg
