yyaxis change ylim for both axes

I would like to change the ylim of the left yaxis. You can see that the ylim entry has no effect at all. I can only change the right side of the yyaxis plot. I appraciate your advice.

Best regards

      %%figure  
      fig = figure (1);
      set(fig, 'Units', 'normalized', 'Position', [0.2, 0.1, 0.5, 0.3]);
      set(0,'defaulttextInterpreter','latex') 

      %%Plot data
      %First subplot
      ax1 = subplot(121)    
      x1 = linspace(1, 1000);
      y11 = x1.^2;
      y12 = x1;
      yyaxis left
      ylim([1, 100]);         % Has no effect. Why? 
      plot(x1,y11,'LineWidth',1.5);        
      grid on   
      yyaxis right
      plot(x1,y12,'LineWidth',1.5);

      %Second subplot
      ax2 = subplot(122);
      plot(x1,exp(x1),'LineWidth',1.5);
      grid on;

Thanks for the advice. I could read the limits of both axes in the variables YLL and YLR. But i could not change them. Do you know how to do that? There is not a proper solution on the page linked to that I can transform into my routine.

clear all
close all

%%figure
fig = figure (1);
set(fig, 'Units', 'normalized', 'Position', [0.2, 0.1, 0.5, 0.3]);
set(0,'defaulttextInterpreter','latex')

%%Plot data
%First subplot
ax1 = subplot(121)
x1 = linspace(1, 1000);
y11 = x1.^2;
y12 = x1;

yyaxis left
plot(x1,y11,'LineWidth',1.5);

yyaxis right
plot(x1,y12,'LineWidth',1.5);

YLL = ax1.YAxis(1).Limits        %limits of left side
YLR = ax1.YAxis(2).Limits        %limits of right side  
hAxes(1).YAxis(1).Limits = ([0, 100]);      % change limits of left side
                                            % doesn't work

%Second subplot
ax2 = subplot(122);
plot(x1,exp(x1),'LineWidth',1.5);
grid on;

ax1.YAxis(1).Limits = ([0, 100]);      % change limits of left side

Of course. I placed the wrong variable. ^^ Thank you.
