Hi, Please how can I save multiple figurea as png into a single folder? I tried this although is "fig" but it only save the last image.
path = 'C:\fig_test' ;
N = 6 ;
for k = 1:N
% theta vs x at point x=0 and y=0
figure(1)
hold on
lgd = ['\xi = ',num2str(xivals(i))];
plot(xarray, squeeze(theta(i, yl, 1:nx, nt)), 'DisplayName',lgd)
xlabel('y[m]')
ylabel('\theta [rad]')
xlim([xmin xmax])
hold off
legend('Location','best')
% velocity in x-direction vs y
figure(2)
hold on
plot(yarray, u(i, 1:ny, xl, nt), 'DisplayName',lgd)
xlabel('y[m]')
ylabel('u [m/s]')
hold off
legend('Location','best')
% velocity in y-direction vs y
figure(3)
hold on
plot(yarray, squeeze(v(i, 1:ny, xl, nt)), 'DisplayName',lgd)
xlabel('y[m]')
ylabel('v [m/s]')
hold off
legend('Location','best')
% theta vs time at x=0 and y=0
figure(4)
hold on
plot(tarray, squeeze(theta(i, yl,xl, 1:nt)), 'DisplayName',lgd)
xlabel('time [sec]')
ylabel('\theta [rad]')
hold off
legend('Location','best')
% theta vs x at x from 251 to 301 and y=0
figure(5)
hold on
plot(xarray(251:301), squeeze(theta(i, yl, 251:301, nt)), 'DisplayName',lgd)
xlabel('x [m]')
ylabel('\theta [rad]')
hold off
legend('Location','best')
% velocity in x-direction vs x at x from 251 to 301 and y=0
figure(6)
hold on
plot(xarray(251:301), squeeze(u(i, yl, 251:301, nt)), 'DisplayName',lgd)
xlabel('x [m]')
ylabel('v [m/s]')
hold off
legend('Location','best')
filename = [path, filesep, 'myfigure',num2str(k)] ;
savefig(filename)
end
end

Hi Walter,
Thank you I have been abel to do using this:
FigList = findobj(allchild(0), 'flat', 'Type', 'figure');
for iFig = 1:length(FigList)
FigHandle = FigList(iFig);
FigName = ['Fig' num2str(iFig)];
saveas(FigHandle, fullfile(figpath, [FigName '.png']));
end
