Set LineWidth when calling plot function.
plot(rand(10, 1), rand(10, 1), 'bo','LineWidth', 2)

It's better to post a new question, but regardless you can access the ax children and modify the properties as desired:
H = tf([2 5 1],[1 3 5]);
pzmap(H)
grid on
ax = gca;
li = ax.Children(1).Children;
for k = 1:numel(li)
li(k).LineStyle = "-";
li(k).LineWidth = 2;
end

What if we need thin line but thicker marker edges?

@Ive J, Please I would like you to help me on this problem of mine, thank you
Given the following elements of matrix A, three matrices are intended to be generated using different variable D as D = 0, D = 4 and D = 70. The poles resulting from this matrices are to be plotted using different Marker, and the marker is inted to be bold, not necessarily big in size. I tried but im getting the error
''Assigning to 2 elements using a simple assignment statement is not supported. Consider using comma-separated list assignment''.
Any assistance would be highly appreciated.
Thank you

Look at PZP. It's an array so you need to assign each one, one at a time. Perhaps like
for k = 1 : numel(PZP)
PZP(k).Marker = '*';
PZP(k).MarkerSize = 8;
PZP(k).Color = 'y';
end

@Image Analyst, please i got this error while using your suggeted input
Unrecognized function or variable 'PZP'.
Error in pzmap2 (line 168)
for k = 1 : numel(PZP)
Please ckindly help me effect the corrections in the code.
Thank you
