How to create a circular buffer in MATLAB for continuous measurements in the correct order

Question

I read the: How to create a buffer matrix in MATLAB for continuous measurements?, question. I wanted to know if its possible to store values in sequence instead of in reverse as in the question, without resorting to fliplr (flip left to right) after each iteration?

Answer 1

Front to back:

buffSize = 10;
circBuff = nan(1,buffSize);
for newest = 1:1000;
    circBuff = [circBuff(2:end) newest]
end

circBuff = 991 992 993 994 995 996 997 998 999 1000

Back to front:

buffSize = 10;
circBuff = nan(1,buffSize);
for newest = 1:1000;
    circBuff = [newest circBuff(1:end-1)]
end

circBuff = 1000 999 998 997 996 995 994 993 992 991

Answer 2

buffSize = 10;
circBuff = nan(1,buffSize);
for newest = 1:1000;
    circBuff = [circBuff(2:end), newest]
   %circBuff = [newest circBuff(1:end-1)] %reverse direction

end

I have tested this, it takes no appreciable time to run in MATLAB. The profiler did not find any bottlenecks with the code.
