I have two plot in a same figure. I need to set text box containing '(a)' and '(b)' in the plots. I can just put them using Insert command but I need the text box to be in the same position of their respective plot (e.g.-bottom left). I have already used legend command once to define the graphs inside the plot. What command and code can I use for this. The code to generate the figure is:
t2=0:0.001:2
a=1*sin(2*pi*5*t2)
b=0.5*sin(2*pi*5*t2)
t = tiledlayout(1,2,'TileSpacing','Compact','Padding','compact');
nexttile
plot(t2,a,'g',LineWidth=5)
legend('First wave')
ylim([-3 3])
ax = gca;
ax.GridLineWidth = 1.5;
ax.GridLineStyle = '--';
ax.GridAlpha = 0.9;
ax.LineWidth=4;
ax.FontWeight = 'bold';
nexttile
plot(t2,b,'r-.')
legend('Second wave')
ylim([-3 3])
ax = gca;
ax.GridLineWidth = 1.5;
ax.GridLineStyle = '--';
ax.GridAlpha = 0.9;
ax.LineWidth=4;
ax.FontWeight = 'bold';
I have attached a image to have the better understanding of my requirement.

You asked this question a month ago, and I answered it at that time:

Just change the texts' Positions to be something like 0.1,0

The issue is that the plots are now different. The plots themselves can not be put in a loop. I have to put them seperately.

Ran in:
You could put them in a loop, but that doesn't matter.
Just make two text calls:
t2=0:0.001:2;
a=1*sin(2*pi*5*t2);
b=0.5*sin(2*pi*5*t2);
t = tiledlayout(1,2,'TileSpacing','Compact','Padding','compact');
nexttile
plot(t2,a,'g',LineWidth=5)
legend('First wave')
ylim([-3 3])
ax = gca;
ax.GridLineWidth = 1.5;
ax.GridLineStyle = '--';
ax.GridAlpha = 0.9;
ax.LineWidth=4;
ax.FontWeight = 'bold';
text(0.02,0.01,'(a)', ...
'Units','normalized', ...
'VerticalAlignment','bottom', ...
'FontWeight','bold')
nexttile
plot(t2,b,'r-.')
legend('Second wave')
ylim([-3 3])
ax = gca;
ax.GridLineWidth = 1.5;
ax.GridLineStyle = '--';
ax.GridAlpha = 0.9;
ax.LineWidth=4;
ax.FontWeight = 'bold';
text(0.02,0.01,'(b)', ...
'Units','normalized', ...
'VerticalAlignment','bottom', ...
'FontWeight','bold')
