import some cellls data from a program into another one.

Hi all

I've written a program named "a.1" which its output is some cells. Hence this program is too long and time-consuming in running, I have to use just the outputs as the input of another program, which named "a.2" .

For example: following loops and corresponding " ropt_final_matrix{t}(ss,qq)" are the outputs of program a.1.

for  t=1:T

      for ss=1:ns

          for qq=1:nq

             ropt_final_matrix{t}(ss,qq)=ropt_final{t,ss}(qq,1);
          end
      end
  end

I want to use just " ropt_final_matrix{t}(ss,qq)" as the input of program a.2, without frequently running of program a.1.

1.How can I do it?

2.How can I export, save and import some outputs in the form of cells?

Could you please clearly guide me?

Thanks,

save('ropt_final_matrix.mat', ropt_final_matrix)

and in a2,

indata = load('ropt_final_matrix.mat');
ropt_final_matrix = indata.ropt_final_matrix;

By the way, part of the reason your program is so slow is that you are not pre-allocating memory.

ropt_final_matrix = cell(T,1);             %NEW
for  t=1:T
    ropt_final_matrix{t} = zeros(ns, nq);  %NEW
    for ss=1:ns
        for qq=1:nq
           ropt_final_matrix{t}(ss,qq)=ropt_final{t,ss}(qq,1);
        end
    end
end

Thanks for your guidance about tags.

Your loop "for qq" can be removed and replaced with

ropt_final_matrix{t}(ss,1:nq) = ropt_final{t,ss}(1:nq,1);

Also if nq is certain to be the exactly the same as the number of rows in all ropt_final{t,ss} then the 1:nq can be changed to : with no explicit range.
