How to create a list of number separated by commas (not a .csv list)?

I am looking to create a list held in a variable like the following:

1,2,3,4

I am currently using this instead:

a = linspace(1,number_of_lines,number_of_lines)
a = mat2str(a);

But this gives:

[1 2 3 4]

in a 1x9 size box filled with those characters, not:

1,2,3,4

I am re-typing the numbers in separated with commas when the relevant dialogue box appears. For large lists, this is not feasible.

How would I do this automatically?

One approach:

number_of_lines = 4;
a = linspace(1,number_of_lines,number_of_lines);
a_commas = [sprintf('%.0f,',a(1:end-1)) sprintf('%.0f',a(end))]

a_commas =
1,2,3,4

Although by definition, a cell array is a comma-separated list.

I tried this earlier today, could not get it to work! (Maybe typed it wrong)

Many thanks ,exactly what was needed
