I have matrix size (1508 x 19).

I want to do subtraction between rows like Row 1 - Row 2, Row 1 - Row 4, Row 1 - Row 6, Row 1 - Row 8, Row 1 - Row 10, Row 1 - Row 12, Row 1 - Row 14,

Row 1 - Row 16, Row 1 - Row 18.

without changing the size of a matrix and remainng rows like (row 1, 3, 5, 7, 9, 11, 13, 15, 17, 19) stay same in matrix.

Can some one help me please

Thank you in advance...

So what do you want as a result?

A matrix where the first row is row1-row2? The second one row1-row4? and so on?

What is your final goal?
