Understand part of code
显示 更早的评论
Hello, I would appreciate your help, I am new to using Matlab and my programming skills are very basic. Could someone explain to me what this piece of code performs:
axd2i=axd2(:,1);axd2d=axd2(:,2);
axd2i(axd2i==0)=[];axd2d(axd2d==0)=[];
axd2=[axd2i axd2d];
z=0;
y=length (axd2(:,1));
for i=y:-1:1
if y-i+1==axd2(i,2)
z=z+1;
end
end
axd2=axd2(y-z+1:end,:);
It is a program to graph arrows in a structure, but the author is sick with COVID and cannot help me at this time.
Thanks in advance

axd2i=axd2(:,1); % get the first column of axd2
axd2d=axd2(:,2); % get the second column of axd2
axd2i(axd2i==0)=[]; % remove the elements which are zeros
axd2d(axd2d==0)=[]; % remove the elements which are zeroes
axd2=[axd2i axd2d]; % merge them into a column matrix. (May fail if zeroes are different)
z=0; % initialize z with 0
y=length (axd2(:,1)); % get the number of rows/ elements
for i=y:-1:1
if y-i+1==axd2(i,2)
z=z+1;
end
end
axd2=axd2(y-z+1:end,:);
