Formatted string plus list of numbers using sprintf

I would like to display comma-separated records like the following,

Record1,2,8,3,5,2,6,3,7,7,7

Here's my attempt, but is there a less clunky way?

% Make the record label string
iRecord = 1;
strLabel = ['Record' num2str(iRecord)];

% Make the number vector
numberList = round(rand(1,10)*10);

% Turn number vector into a string
numberListIntoString = sprintf('%d,', numberList);
% Remove comma at end
numberListIntoString = numberListIntoString(1:(end-1)); 

% Display the result
disp([strLabel ',' numberListIntoString])

numberList = round(rand(1,10)*10);
s = ['Record',regexprep(num2str([1,numberList]),' +',',')];

BTW, another way to create a vector of random integers between 0 and 10:

randi(11,1,10)-1

I was unfamiliar with regexprep, so thanks. Just for my own learning on regular expressions, here we construct a string using

num2str([1,numberList]) % Space-separated list of numbers, with record number first

The spaces are replaced multiple times ('+') with commas.

[Adam Danz]

num2str([1,numberList]) 

That line adds more than 1 space between each number. The ' +' in the regular expression means search for at least one or more consecutive spaces.

Just for learning, remove that plus sign and see what happens,

numberList = round(rand(1,10)*10);
s = ['Record',regexprep(num2str([1,numberList]),' ',',')];
%                                                ^ only 1 space

If you're using a release that supports string convert your numeric vector into a string using string. Next use join to combine the elements of that string array into one string, each separated by a delimeter. Finally concatenate the result to the end of a header string with +. I separated the steps into four lines for clarity, but you could do it in one.

vec = [1 2 8 3 5 2 6 3 7 7 7]
strvec = string(vec)
str = join(strvec, ',')
S = "Record " + str

I chose to separate "Record" and the first element of the the vector with a space; remove the last character of the string in the last line if you don't want that.

I have 2019a, so string is supported (since 2016b).
