MATLAB: Convert number vector back to segmented string

Question

Hi all

Does anybody know how to convert a number vector back to a "segmented", equispaced string? For example: x=str2num('0:2:6 10:5:30') results in [0 2 4 6 10 15 20 25 30]. But when I have the vector, how can I get back to the string showing the segments, not just the full list of numbers as a string, which is what num2str will result in. Thanks

See:

• FEX: Vector to colon notation
• FEX: vector to string

Note that this procedure is instable: 0:0.1:1 is not equidistant due to the limited numerical precision. But for integers < 2^53-1 the methods are expected to work as expected.
