Is there a way to create a new variable inside a while loop?

I am building a table that checks sets of time stamped data for continuity over specified time intervals.

One of my data sets has 96 subsets which would require 96 loops similar to LOOP 1.

What i would like to do is use a while loop nested inside a while loop functionally similar to loop 2. Is this possible?

    %LOOP 1---------  
            CONTTABLE_170_2 = zeros(9,3);
            CONTTABLE_170_2(:,1) = CONTTABLE(:,1);
            CONTTABLE_170_2(:,2) = CONTTABLE(:,2);

            SIZE_SORT_BIT_170_2 = size(SORT_BIT_170_2);
            SIZE_SORT_BIT_170_2 = SIZE_SORT_BIT_170_2(1,1);

             n=1;
            while n<=9;
                for i=1:SIZE_SORT_BIT_170_2;
                    TIMESTAMP = SORT_BIT_170_2(i,11);
                    TS_LIMIT_LOW = TIMETABLE(n,1);
                    TS_LIMIT_HIGH = TIMETABLE(n,2);

                    if  and(TS_LIMIT_LOW<=TIMESTAMP, TS_LIMIT_HIGH>TIMESTAMP);
                          CONTTABLE_170_2(n,3) = 1;
                    else  CONTTABLE_170_2(n,3) = 2;
                    end

                end
                n=n+1;
            end

    %LOOP 2-------------------
  VARIABLE_VAL = 1;

while VARIABLE_VAL<=96;

          CONTTABLE_170_[VARIABLE_VAL] = zeros(9,3);
          CONTTABLE_170_[VARIABLE_VAL](:,1) = CONTTABLE(:,1);
          CONTTABLE_170_[VARIABLE_VAL](:,2) = CONTTABLE(:,2);

          SIZE_SORT_BIT_170_[VARIABLE_VAL] = size(SORT_BIT_170_[VARIABLE_VAL]);
          SIZE_SORT_BIT_170_[VARIABLE_VAL] = SIZE_SORT_BIT_170_[VARIABLE_VAL](1,1);

           n=1;
          while n<=9;
              for i=1:SIZE_SORT_BIT_170_[VARIABLE_VAL];
                  TIMESTAMP = SORT_BIT_170_[VARIABLE_VAL](i,11);
                  TS_LIMIT_LOW = TIMETABLE(n,1);
                  TS_LIMIT_HIGH = TIMETABLE(n,2);

                  if  and(TS_LIMIT_LOW<=TIMESTAMP, TS_LIMIT_HIGH>TIMESTAMP);
                        CONTTABLE_170_[VARIABLE_VAL](n,3) = 1;
                  else  CONTTABLE_170_[VARIABLE_VAL](n,3) = 2;
                  end

              end
              n=n+1;
          end
  end

" Is this possible?"

Yes.

Should you do it ?

No.

As has been discussed a thousand times on this forum (and others), creating variables is a slow, buggy, and obfuscated way to write code.

The much faster, neater, and better way to achieve this is to use indexing and one variable. Really that is all, it is nothing complicated (unlike that hack code you would need to access multiple variables dynamically).

Read all of the links in my answer to know more about why dynamically accessing variable names is a bad idea.
