Hi
I want to save my images in MATLAB with minimum 300DPI roslution. Following is my figure code (below) and when I try to save with following code (exportgraphics(f,'elastic avo.png','Resolution',300)) I go this error
Undefined function or variable 'exportgraphics'.
Error in PLOTTING (line 24)
exportgraphics(f,'elastic avo.png','Resolution',300)
Figure code is:
f=figure; subplot(121); plot(iters,hist/max(hist),'-b', 'displayname', 'S/N = Infinity','LineWidth',1.5); hold on;
plot(iters,hist_snr/max(hist_snr),'-.r', 'displayname', 'S/N = 50','LineWidth',1.5);
set(gca,'xtick',[0:100:200]); set(gca,'ytick',[0:0.2:1]); ylim([0 1]); title('Elastic inversion')
grid on; set(gca,'GridLineStyle','--'); xlabel('Iterations'); ylabel('Error function'); legend
subplot(122); plot(itr4d,avo4dhist/max(avo4dhist),'-b', 'displayname', 'S/N = Infinity','LineWidth',1.5); hold on;
plot(itesnr,avohist_snr/max(avohist_snr),'-.r', 'displayname', 'S/N = 5','LineWidth',1.5);
set(gca,'xtick',[0:10:50]); set(gca,'ytick',[0:0.2:1]); ylim([0 1])
grid on; set(gca,'GridLineStyle','--'); xlabel('Iterations'); ylabel('Error function'); legend
set(gcf, 'position', [400 285 1127 443]);
exportgraphics(f,'elastic avo.png','Resolution',300)

exportgraphics() is available since 2020a
which release are you using?

so that's your problem. exportgraphics is not available to you. To save at resolution 300dpi, you can e.g. use
print('elastic avo.png','-dpng','-r300')
