I wish to produce an array/vector of strings to use as InputNames and OutputNames on a dynamical system model in something like the following manner (note that the below doesn't work, but illustrates what I'm looking for):
n = 5;
stringVector = {'v' num2str(n)};
in order to produce a vector of strings as such:
stringVector = {'v1', 'v2', 'v3', 'v4', 'v5'}
How can this be done?
Thanks, Olie

Oliver, you could do
n = 5;
for ii = 1:n
stringVector{ii} = strcat('v',int2str(ii));
end
or simply
stringVector = strcat({'v'},int2str((1:5)'));

Oh - I've just discovered, given two vectors of strings, vec1, and vec2, you can produce a concatenation of these vectors with
totalVec = [vec1,vec2]
Thanks for all the help.

There is an undocumented but extremely efficient function for this job:
stringVector = sprintfc('v%d', 1:5)

And a documented one liner:
x = strcat('v',cellstr(num2str((1:5).')))
