I have a 2d plot as shown in attached image, I would like to remove the middle nine marker points in this plot. How can I achieve this? Please provide your suggestion. Thank you all.
clear
clc
nx=5;
ny=5;
x=linspace(0,1,nx);
y=linspace(0,1,ny);
[X,Y]=meshgrid(x,y);
x1=linspace(1/4,1/1.33333,nx);
y1=linspace(1/4,1/1.33333,ny);
[X1,Y1]=meshgrid(x1,y1);
hold on
plot(X,Y,'k',Y,X,'k');
plot(X,Y,'ro',Y,X,'ro','MarkerFaceColor',[1,0.6,0.6]);
plot(X1,Y1,'k',Y1,X1,'k');
axis square

Which MATLAB release? The ability to adjust this easily is relatively new.

If the goal is to remove all of the markers except for the 'outer' ones, then try this. This should be relatively generic (independent of the size specified by nx and ny), if not elegant.
Replace this line:
plot(X,Y,'ro',Y,X,'ro','MarkerFaceColor',[1,0.6,0.6]);
with these two lines:
Youter(2:end-1,2:end-1)=NaN;
plot(X, Youter, 'ro', 'MarkerFaceColor', [1, 0.6, 0.6])
If I misinterpreted your goals, post a comment making them more clear.

With recent MATLAB, you can set the MarkerIndices property of line objects; see https://www.mathworks.com/help/matlab/creating_plots/create-line-plot-with-markers.html#bvcbmlx-1
You are plotting an array of Y so one line object would be generated for each column. Record the output of plot() in order to get those handles. Leave the first and last of the handles alone and set the others to have only 1 and their length in MarkerIndices property.
