You can use colon notation to specify the increment size. For example
Columns 1 through 7
2.1200 2.1300 2.1400 2.1500 2.1600 2.1700 2.1800
Columns 8 through 11
2.1900 2.2000 2.2100 2.2200
But as Stephen mentioned, your finite precision floating point number will not be able to provide the precision you require. You will need the symbolic toolbox.
Note that I used a char array as input to vpa() to maintain precision. You can read more on this here. The above statement is theoretically correct but I doubt you will be able to store such large array. The increment size you need will require several petabytes of memory.
