I cant figure out how to print a = 1:10 as 1,2,3,4,5,6,7,8,9,10

(Assuming the values are integers which can be represented in double precision) With newer versions, you can use strings like this -
a = 1:10;
b = strjoin(string(a), ',')

regexprep( mat2str(a), {'\[', '\]', '\s+'}, {'', '', ','})
or
[sprintf('%d,', a(1:end-1)), sprintf('%d', a(end))];
or
temp = sprintf('%d,', a);
temp(end) = []; %get rid of trailing comma

a = 1:10;
sprintf("%s", strip(sprintf("%d,", a), ","))
% ans = "1,2,3,4,5,6,7,8,9,10"
It has the advantage that one can simultaneously add characters (like surrounding brackets) to the string formatting, control the number formatting (like decimal places), and use non-indexable input (like function calls), e.g.:
sprintf("[%s]", strip(sprintf("%.2f,", linspace(1,10,10)), ","))
% ans = "[1.00,2.00,3.00,4.00,5.00,6.00,7.00,8.00,9.00,10.00]"
