How to make the marker width more thicker
显示 更早的评论
I have plot the data but what i want is to make the marker more thicker, so that it can be more clearly visible . I have attached the code .i would be grateful if you could help me .Thank you in adva

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

"Line width, specified as a positive value in points, where 1 point = 1/72 of an inch. If the line has markers, then the line width also affects the marker edges."

@Ive J, Hi, I have a similar problem, but linewidth is not working for marker on pzmap, pls kindly assist and if i intend to connect the marker together, please how do I adjust my program to implement that? Thank you
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?

The plot function provides the name-value arguments Marker, MarkerIndices, MarkerEdgeColor, MarkerFaceColor, and MarkerSize so that you can customize the appearance of markers. Use the name-value argument MarkerSize to change the size of the marker.

@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

Beginning in R2024b, the MarkerSize in a "pzplot" can be updated using the property.
pzp = pzplot(zpk(-1,[-2 -3],1));
pzp.Responses(1).MarkerSize = 10;
There are also properties on other linear analysis plots that allow customization of the style.
