Thread Subject: conversion

Hi,
Does anyone know how to convert a series of numbers into a
single value with a colon inbetween the numbers. For
example,

a=5;b=75,c=8;

And I would like to produce:

5:75:8

Use the 'disp' command, it displays text. You need to convert your
numbers to a text format though, with the 'num2str command. Type 'doc
disp' in you comand line for help.

the code for displaying what you asked is:
disp([num2str(a) ':' num2str(b) ':' num2str(c)]);


Hope this helps,
Adam

It depends on what you need to do, but you may use a cell
format and the command num2cell.

What do you mean by "single value"? A string (=character
array) used for display purposes? If so,

sprintf('%d:%d:%d',a,b,c)

will do.

Also note that in matlab the command A:B:C means a list of
numbers running from A to C with steps B

  If I understand you correctly, you can only do that if your series is an
arithmetic progression - that is, if all the successive differences are equal
(within rounding error.) If x is a row vector with such a sequence (with at
least two elements,) then you can use

 y = x(1):x(2)-x(1):x(end);

in place of x. However, note that rounding errors can cause very small
differences between y and x.

  Is this what you are asking for? Your example is rather puzzling since it
consists of the single scalar 5. The next value after 5 would be 5+75=80
which is beyond 8 and therefore not in the series.
