How can i round numbers to multiple of any number?

Hi everbody

There are commands for rounding of numbers in MATLAB like ceil, floor etc., but if we should round the numbers to multiple of any number (toward negative infinity), what kind of a code can be written?

For ex. multiples of 8: 8, 16, 24, 32...

Numbers: 9, 13,18, 25,34...

Results: 8, 8, 16, 24, 32...

Is there any code for round these numbers to multiple of 8 (toward negative infinity)?

>> V = [9,13,18,25,34];
>> N = 8;
>> N*floor(V/N)
ans =
    8    8   16   24   32
