I’m running a code for different files, however I need to sore the results in a cell array without overwriting the info in each cell, I mean every time I run the code for a different file as a result it creates a second row of data in the cell array. Thanks.

@Nicolas Broch here is the code , everytime I run this for a different file, it overwrites the variables mn1,md1, and so on,, the idea is to accumulate the results in a cell array without overwriting the previous one.

tab8=uitab('Title','Position of layers (Distribution) (km)');
ax8=axes(tab8);
sgtitle(tab8, 'Position of layers (Distribution) (km)');
mnn1=cellfun(@mean,locs);
ksdensity(mnn1,'Parent',ax8);
ax8.Children(1).Color = 'Black';
ax8.Children(1).LineWidth = 1.2;
xlabel(['Position of layers in altitude/km LT 24h, date: ',R(1).Info.Name(1:8)],'FontSize',9,'FontName','Arial','color','default');
yticks('');
ax8.XGrid = 'on';
ax8.GridAlpha = 0.9;
ax8.GridLineStyle = '-';
ax8.GridColor = [0.3010 0.7450 0.9330];
ax8.Color = 'y';
ylim(ax8,[-inf inf]);
hold;
% mean
mn1=mean(mnn1,'omitnan');
mn11=xline(mn1,'Parent',ax8);
ax8.Children(1).Color = 'Red';
ax8.Children(1).LineWidth = 1.2;
ax8.Children(1).LineStyle = '-';
hold;
% median
md1=median(mnn1,'omitnan');
md11=xline(md1,'Parent',ax8);
ax8.Children(1).Color = '#7E2F8E';
ax8.Children(1).LineWidth = 1.2;
ax8.Children(1).LineStyle = '--';
hold;
%mode
mod1=mode(mnn1,'all');
mod11=xline(mod1,'Parent',ax8);
ax8.Children(1).Color = 'cyan';
ax8.Children(1).LineWidth = 1.2;
ax8.Children(1).LineStyle = ':';
hold;
legend('Layering distribution',sprintf('Mean(km) :%7.2f',mn1),sprintf('Median(km) :%7.2f',md1),sprintf('Mode(km) :%7.2f',mod1),'FontSize',7,'Location','northeast','NumColumns',1);
legend('boxoff');
hold;
%% width of layers per day
tab9=uitab('Title','Width of layers (km)');
ax9=axes(tab9);
sgtitle(tab9, 'Width of layers (km)');
mnn11=cellfun(@mean,widths);
histfit(mnn11);
%mean
mn11=mean(mnn11,'omitnan');
mn111=xline(mn11,'Parent',ax9);
ax9.Children(1).Color = 'Green';
ax9.Children(1).LineWidth = 1.2;
ax9.Children(1).LineStyle = '-';
hold;
%median
md11=median(mnn11,'omitnan');
md111=xline(md11,'Parent',ax9);
ax9.Children(1).Color = '#7E2F8E';
ax9.Children(1).LineWidth = 1.2;
ax9.Children(1).LineStyle = '--';
hold;
%mode
mod11=mode(mnn11,'all');
mod111=xline(mod11,'Parent',ax9);
ax9.Children(1).Color = 'cyan';
ax9.Children(1).LineWidth = 1.2;
ax9.Children(1).LineStyle = ':';
hold;
xlabel(['Width of layers (km), LT 24h date: ',R(1).Info.Name(1:8)],'FontSize',9,'FontName','Arial','color','default');
yticks('');
legend('Data','Normal distribution',sprintf('Mean(km) :%7.2f',mn11),sprintf('Median(km) :%7.2f',md11),sprintf('Mode(km) :%7.2f',mod11),'FontSize',7,'Location','best');
legend('boxoff');
ax9.Color = 'Yellow';
hold;

@Stephen Cobeldick Apparently, it doesn't explain the fact how you can create a cell array or a vector without overwriting the results of the previous run.
