i need to round off some numbers to nearest quarter , with an option to round up or round down to nearest quarter
for e.g. For an array for (5,1) with following values
1373.698
1385.024
1394.82
1400.436
1396.532
output for rounding up to closest 0.25 will result in
1373.75
1385.25
1395.00
1400.50
1396.75
output for rounding down to closest 0.25 will be
1373.50
1385.00
1394.75
1400.25
1396.50
I am not sure how to create such a function which gives this output, please help .

Hi,
I think you are looking for:
in = [1373.698
1385.024
1394.82
1400.436
1396.532];
%round up
up = floor(in) + ceil( (in-floor(in))/0.25) * 0.25
%round down
down = floor(in) + floor( (in-floor(in))/0.25) * 0.25

The previous answers look more complex than needed
%round up
up = ceil(in * 4) / 4;
%round down
down = floor(in * 4) / 4;

Can you make this a single function, please? - - It would be then a complete answer to the question, at least for me. I extended my case here https://se.mathworks.com/matlabcentral/answers/309097-how-to-round-up-to-closest-0-0-or-0-5-in-array

If you want to round to the nearest 0.25 both up and down, then do:
%roudn to nearest 0.25
updown = round(in * 4)/4;
