Hi Vijender. How large is the array you used? Did you download closest.m from here (Matlab File Exchange)?. Thanks.

Please, see also mat2colon.m here http://www.mathworks.com/matlabcentral/fileexchange/30797-mat2colon

I forgot to mention that mat2colon.m needs vect2colon.m in order to work. You can find it here http://www.mathworks.com/matlabcentral/fileexchange/22076

This function takes a hell lot of time for very large arrays. Is there any fast function available for getting closest value.

'Closest' syntx is not found in MATLAB 2012b. Can you please tell me in which matlab version this syntx is found.

I suggest to merge the two submissions mat2colon and vec2colon into one.

20 Mar 2011 Vector to colon notation Converts a vector into a string with its MATLAB colon notation (single resolution). Author: Javier Lopez-Calderon Luong, Bruno

I rather like the idea, but I was disappointed mainly by the fact that the function returns a string instead of number.

- EVAL would be necessary to build back the original array. I would prefer COLON rather than EVAL.
- The precision get lost in the way

vect2colon([0:0.1234567890123456:1],'Class','double')

ans =

0:0.12346:0.98765

I would prefer empty input returns '[]' for the following reason:

>> a=eval(vect2colon([]))
??? Error: Expression or statement is incomplete or incorrect.

The engine could also be better, for example this command takes very long to complete:

>> vect2colon([0:1e-7:1])

and the casting dvec to SINGLE is a clear sign of the limitation of the transformation.
