insert elements of array in a string one by one

i have a string containing url 'http://www.upsc.gov.in/cgi-bin1/ENGG/Marks/engg_wq_marks_response.pl?roll_no= 098909 ---'

the digits in the bold are to be changed at every iteration of the for loop and the new element of an array are to be inserted. But MATLAB does not consider a variable inside a string.

How can i solve this problem?

Thanks in advance.

This is easy using sprintf, and the documentation contains plenty of examples.

Depending on the inputs something like this might help:

for k = 98900:98999
  S = sprintf(['http://www.upsc.gov.in/cgi-bin1/ENGG/Marks', ...
               '/engg_wq_marks_response.pl?roll_no= %06d ---'], k)
end

Or:

C = {'098909', '098910', '098911'};
for k = 1:3
  S = sprintf(['http://www.upsc.gov.in/cgi-bin1/ENGG/Marks', ...
               '/engg_wq_marks_response.pl?roll_no= %s ---'], C{k})
end

If you provide the definition for the changing part of the string, a matching answer is more likely.
