MATLAB: How to convert a numerical vector into a comma-delimited string

csvMATLAB

Given a numerical vector, how do I convert it into a comma-delimited string?

For example, if

n = [12345 6789 10234 3452]

convert n to

12345,6789,10234,3452

n = [12345 6789 10234 3452];
allOneString = sprintf('%.0f,' , n);
allOneString = allOneString(1:end-1);% strip final comma

SUM is memory bound. The issue directly relates to throughput on the CPU(s). The following results illustrate this:

1. Two cores share one BUS

>> x = rand(1000);
>> tic; mean(mean(x)); toc
Elapsed time is 0.002357 seconds.

2. Two cores with two BUSES

>> x = rand(1000);
>> tic; mean(mean(x)); toc
Elapsed time is 0.001802 seconds.

3. Using ‘-singleCompThread’:

>> x = rand(1000);
>> tic; mean(mean(x)); toc
Elapsed time is 0.002660 seconds.
