Hi, I have this piece of code:

clear all;
close all;
x=(1:1:50);
y=x.^2;
z=x.^3;
t=-10*z;
aaa=[y; z; t];
for i=1:size(aaa,1);
  figure(i);
  plot(x,aaa(i,:));
  xlabel('Time [s]','FontSize',15);
  if i==1
      axis([0 30 0 1000]);
      ylabel('Temp[K]','FontSize',15);
  else if i==2
          axis([0 35 0 60000]);
          ylabel('Heat[W]','FontSize',15);
      else if i==3
              axis([0 40 -60000 0]);
              ylabel('Flow[Kg/s]','FontSize',15);
          end
      end
      saveas(gcf,'H:\MATLAB\PI610_fig\APRM_fig022.png');
  end
end

How can I export multiple figures having a predefined path, cutting also the blak space(Here Aprmfig022.png is overwritten)? Thank you.

y=x.^2;
z=x.^3;

for i=1:size(aaa,1);
  figure(i);
  plot(x,aaa(i,:));
  xlabel('Time [s]','FontSize',15);
  if i==1
      axis([0 30 0 1000]);
      ylabel('Temp[K]','FontSize',15);
  elseif i==2
      axis([0 35 0 60000]);
      ylabel('Heat[W]','FontSize',15);
  elseif i==3
      axis([0 40 -60000 0]);
      ylabel('Flow[Kg/s]','FontSize',15);
  end
  saveas(gcf,sprintf('H:\MATLAB\PI610_fig\APRM_fig%d.png',i))
end
