I want to know on how to reshape geographyc data from 100 x2 mtrix size into 4X25. Is there any one can help me to reshape my data into 4 x 25 matriks data?

Here is my data.

You ask for a 4x25 matrix, yet when you give us the desired shape you show a 2x6 matrix.

So, we still have absolutely no idea what you want. Do you want

1a   5a  1b  5b  
2a   6a  2b  6b
3a   7a  3b  7b
4a   8a  4b  8b

1a   1b  2a  2b 
3a   3b  4a  4b 
5a   5b  6a  6b
7a   7b  8a  8b

or something else entirely?

Not sure which orientation you want but adapt which one suits you the best from the below:

reshape(data.',4,[]).' % this suits your comment
reshape(data.',4,[])
reshape(data,[],4).'
reshape(data,4,[])

Thank you Guillaume it done to re arrange lat and lon.

Great

Dear Guillaume let me ask simple question, how to add/insert a comma in between two pair of lat and lon.

lat1 lon1,lat2 lon2, lat3 lon3,...,lat50lon50

Without knowing the final goal, I can't make specific recommendations. The lines below convert the matrix to a cell array of stings which will help you get started.

dataCell = strsplit(sprintf('%.2f %.2f, |', data'),'|'); 
dataCell = reshape(dataCell(1:end-1), 4, 25);

The result...

 4×25 cell array
  Columns 1 through 6
    {'73.50 42.65, '}    {'73.70 42.65, '}    {'73.90 42.65, '}    {'74.10 42.65, '}    {'74.30 42.65, '}    {'74.50 42.65, '}
    {'73.55 42.65, '}    {'73.75 42.65, '}    {'73.95 42.65, '}    {'74.15 42.65, '}    {'74.35 42.65, '}    {'74.55 42.65, '}
    {'73.60 42.65, '}    {'73.80 42.65, '}    {'74.00 42.65, '}    {'74.20 42.65, '}    {'74.40 42.65, '}    {'74.60 42.65, '}
    {'73.65 42.65, '}    {'73.85 42.65, '}    {'74.05 42.65, '}    {'74.25 42.65, '}    {'74.45 42.65, '}    {'74.65 42.65, '}

You could combine the rows like this

[strcat(dataCell{1,:}); strcat(dataCell{2,:}); strcat(dataCell{3,:}); strcat(dataCell{4,:})]

The result...

ans =
  4×300 char array
