Need help to write general syntax for matlab program for combining results of all inputs

If i have a matlab program which requires input d. suppose i want to get results for d=8 and d=9. i can run program separately like- every time for d=8 and get result, then for 9 and get result.

for example for d=8, i get

 A=
                              1     2     

                              2     3

then again for d= 9, i get

    A=
                              1     7     

                              0     6

How can i modify my program to store result from previous input, so that it display result as for d= 8, d= 9 together as

                               *1     2     

                               2     3*

                               1     7     

                               0     6

You could use arrayfun to stash your outputs into a cell array and then cell2mat to transform that array into a matrix of of the right shape. e.g: assuming your program (function) is called myprogram:

proginputs = [8 9]; %whatever you want them to be
progoutputs = arrayfun(@myprogram, proginputs, 'UniformOutput', false); 
outputmatrix = cell2mat(progoutputs'); transposed as you want the outputs concatenated in column.

Or as a one liner:

outputmatrix = cell2mat(arrayfun(@myprogram, [8 9], 'UniformOutput', false)');

Here is a sure-fire but not necessarily efficient way. This should combine the results of generating lots of 2x2 matrices that are just whatever number d is.

Replace my A with how to solve for yours, and you are good to go. :)

for d = 1:10     % Change this to however many d's you want to go through

A = d*ones(2,2); %Replace this with however you generate A

combined_results(2*d-1,1) = A(1,1);
combined_results(2*d-1,2) = A(1,2);
combined_results(2*d,1)   = A(2,1);
combined_results(2*d,2)   = A(2,2);

end

combined_results

just perform the standard concatenation of

 Results = [];
 for d=8:9
     Results = [Results; your_function(d)];
 end

which you stick your function results at the end of results.
