I have an if statement
for ind = 1:MAX_ITER
if(mod(ind, 1500) == 0)
h = findobj(gca,'Type','line');
x=get(h,'Xdata');
y=get(h,'Ydata');
z=[x,y];
H_XX = z{2,1};
H_YY = z{2,2};
filename=['test',num2str(ind),'.mat'];
save(filename)
end
end
How can i save the 'H_XX' and 'H_YY' of the entire loop in a single file ?

count = 0 ;
iwant = cell([],1) ;
for ind = 1:MAX_ITER
if(mod(ind, 1500) == 0)
h = findobj(gca,'Type','line');
x=get(h,'Xdata');
y=get(h,'Ydata');
z=[x,y];
H_XX = z{2,1};
H_YY = z{2,2};
count = count+1 ;
iwant{count,1} = [H_XX H_YY] ;
end
end
iwant = cell2mat(iwant) ;
iwant gives you data when the loop goes inside if. You can save it into a file you want.

It is simpler to avoid generating too many values (and then using mod to select which values you want to use) because then you can trivially preallocate an output array of the correct size:
vec = 1500:1500:MAX_ITER;
out = cell(numel(vec),2);
for k = 1:numel(vec)
...
out(k,:) = [x,y];
end
save('test.mat','out')
This trivially avoids expanding the output array on each iteration:
