MATLAB: Saving heatmaps as image

heatmapimageMATLABsavesubplot

I want to save 3 images as jpg of dimension 227×227-
  1. Heatmap1
  2. Heatmap2
  3. Subplot of Heatmap1 and Heatmap2
This is the code for my heatmaps:
% Heatmap1
        subplot(2,1,1)
        heata=heatmap(n2E);
        heata.GridVisible='off';
        colormap(jet)
        heata.ColorbarVisible='off';
        caxis([-0.4440 0.8660 ])
        heata.FontColor='none';
       
%Heatmap2
        subplot(2,1,2)
        
        heatp=heatmap(n2);
        heatp.GridVisible='off';
        colormap(jet)
        heatp.ColorbarVisible='off';
        caxis([0   4095])
        heatp.FontColor='none';
        
%subplot of heatmaps
        ha=get(gcf,'children');
        set(ha(1),'position',[.1 .1 .8 .4])
        set(ha(2),'position',[.1 .5 .8 .5])
I was able to save the subplot of the heatmaps using:
 Path=strcat('C:\Users\Admin\Documents\MATLAB\h3.jpg';
 saveas(gcf,Path);
I'm not able to save Heatmap1 and heatmap2 as seperate image files as well.
Please help me out with the code.

If you are using R2020a, you can use exportgraphics() ans specify the handle of graphic object.
n2E = rand(10); % for example
n2 = rand(10);
% Heatmap1
        subplot(2,1,1)
        heata=heatmap(n2E);
        heata.GridVisible='off';
        colormap(jet)
        heata.ColorbarVisible='off';
        caxis([-0.4440 0.8660 ])
        heata.FontColor='none';
       
%Heatmap2
        subplot(2,1,2)
        
        heatp=heatmap(n2);
        heatp.GridVisible='off';
        colormap(jet)
        heatp.ColorbarVisible='off';
        caxis([0   4095])
        heatp.FontColor='none';
        
%subplot of heatmaps
        ha=get(gcf,'children');
        set(ha(1),'position',[.1 .1 .8 .4])
        set(ha(2),'position',[.1 .5 .8 .5])
        
        exportgraphics(gcf, 'figure.jpg');
        exportgraphics(ha(1), 'subplot1.jpg');
        exportgraphics(ha(2), 'subplot2.jpg');
