for i=1:length(fileList)
    a=importdata(fileList(i).name);
    avec=a;
    avec(:,1:3)=[];
    proj(:,1)=avec(:,1)
    proj(:,2)=avec(:,2)
    proj(:,3)=avec(:,3)
    
    projx=reshape(proj(:,1),[250,150]);
    projy=reshape(proj(:,2),[250,150]);
    projz=reshape(proj(:,3),[250,150]);
    
    projxnew=projx.';
    projynew=projy.';
    projznew=projz.';
    
    subplot(1,3,1);
    imagesc(xlimits,ylimits,projxnew,climx);
    pbaspect([2.5 1.5 1])
    xlim(xlimits);
    ylim(ylimits);
    subplot(1,3,2);
    imagesc(xlimits,ylimits,projynew,climy);
    pbaspect([2.5 1.5 1])
    xlim(xlimits);
    ylim(ylimits);
    
    subplot(1,3,3);
    imagesc(xlimits,ylimits,projznew,climz);
    pbaspect([2.5 1.5 1])
    xlim(xlimits);
    ylim(ylimits);
    
    f=figure;
    f = strcat(num2str(i),'.png');
    saveas(gcf,f);
    
end

在 MATLAB Online 中打开

Remove the line

f=figure;

at the bottom of the loop, but open a new figure on top:

for i=1:length(fileList)
    FigH = =figure;
    ... your code
        
    FileName = strcat(num2str(i),'.png');
    saveas(FigH, FileName);
    delete(FigH);
end
