i have array like this a = 50 60 70 80 and want to make each entity comma seperated i.e 50,70,80,90 how i can do this?

it can be done by concetnation method?

Neither the input nor the output is defined exactly. I guess that the input is a numerical vector like:

a = [50, 60, 70, 80]

and the output should be a string:

s = '50, 60, 70, 80'

I assume, that the omitted '60' and the added '90' is a typo only.

Please be as exact as possible, when you ask a question in the forum. Guessing the details means usually a waste of your and out time. Thanks.

A= [20,30,40,50]';
comma = ones(size(A))* ',';
B = [num2str(A) char(comma)];

a = [50, 60, 70, 80]
s = sprintf('%d, ', a);
s(end-1:end) = [];  % Remove the trailing ', '
