I can't use csview() command, when I run the program, my command shows an error (' Unrecognized function or variable 'csview'.' )
and my code
% generate two clusters of color points
rgb = min(abs(randn(2000,3).*[0.5 0.3 0.1] + [0 0 0]),1);
rgb = [rgb; 1-rgb];
xyz = rgb2xyz(rgb);
xlabel('X');
ylabel('Z');
zlabel('Y');
hold on;
% plot the points
scatter3(xyz(:,1),xyz(:,3),xyz(:,2),10,rgb,'.');
view(3); grid on;
axis equal
axis([0 1 0 1.1 0 1]);
set(gca,'color','k','gridcolor','k','gridalpha',0.3)
set(gca,'projection','perspective');
view('xyz','alpha'0.2,'invert',1); hold on; % do this before scatter3()
how to fix this
many thanks ^^

You need to download this FEX submission (by clicking on the big blue "Download button"):
https://www.mathworks.com/matlabcentral/fileexchange/53786-image-manipulation-toolbox
and unzip it onto your MATLAB Search Path or into the current folder.
Have you done that?

I have downloaded and unzipped them according to the path in (C:\Users\DELL\Downloads\_temp_matlab_R2021a_win64\bin\win64)
but my program still shows the above error, is there any other solution, many thanks

Do NOT add, remove, alter, edit, or change in any way the files in the MATLAB installation directories!
This is a very odd path, it looks like an installation or temporary installation path:
C:\Users\DELL\Downloads\_temp_matlab_R2021a_win64\bin\win64
A BIN directory is a big red flag, telling you "no, do not work in this directory". As a beginner you should put all of your own files (and any files you download, etc) into the default MATLAB startup directory, which on Windows is:
C:\Users\<user>\Documents\MATLAB
https://www.mathworks.com/help/matlab/matlab_env/matlab-startup-folder.html
You can also save MATLAB files in other locations and change the Search Path to suit:

but NEVER in any installation directories of ANY application installed on your computer.
