Change variable name on each iteration in for loop MATLAB

Question

I have large array P which is changing size and values in each iteration. I need to be able to change the title of my output array to match the given iteration, i.e. for bin 1.4 I would like output to be p1.4 or p14.

Can anyone help?

for bin = 1:0.1:2;
    rows = find(DAT(:,27) > bin);
    p{bin} = DAT(rows,:);
end

fprintf('p%.1f\n', bin); ?

If I understood you correctly, the code is

for bin = 1:0.1:2;
    rows = find(DAT(:,27) > bin);
    current_p = DAT(rows,:);
    eval(sprintf('p%0.f=current_p;', bin * 10));
end

But why do you need this? Consider use a smarter container like containers.Map:

p = containers.Map('KeyType', 'double', 'ValueType', 'double')    
for bin = 1:0.1:2
     rows = find(DAT(:,27) > bin);
     p(bin) = DAT(rows,:);
end
disp(p(1.2))

It could be more convinient.

how about

bins = 1:0.1:2;
for ii = 1: numel(bins)
    bin = bins(ii);
    rows = find( DAT(:,27) > bin );
    p{ii} = DAT(rows,:);
end
