MATLAB: How to write data in an appointed data format

data format output write

Dear colleagues,
I have a column data:
44566
44567
44568
44565
44566
4565
44563
99999
44561
44563
44564
…
but I want to convert my data into the following data format, e.g., 6f12.4 would imply six values per row each twelve characters long with four decimal places.
4565.000 44566.000 44567.000 44568.000 44565.000 44566.000
4565.000 44563.000 99999.000 44561.000 44563.000 44564.000
…..
 Could you give me some good suggestions? Many thanks!

It would imply that in FORTRAN but not MATLAB.
You would have to do something like this:
v = [44566
    44567
    44568
    44565
    44566
    4565
    44563
    99999
    44561
    44563
    44564
    44567];
fid = 1;                                    % Here ‘1’ Is ‘stdout’, The Command Window, But You Would Use The ‘fopen’ Function To Write To A File
fprintf(fid, '%12.4f\t%12.4f\t%12.4f\t%12.4f\t%12.4f\t%12.4f\n', v)
producing:
    44566.0000    44567.0000    44568.0000    44565.0000    44566.0000     4565.0000
    44563.0000    99999.0000    44561.0000    44563.0000    44564.0000    44567.0000
