for i = 1:10
Si = Example(i,:)
end
So I have this line of code and I want answers S1, S2, S3, S4 etc, however I only get Si for every answer and if i replace Si with S(i) or S{i} the code doesn't work , so how can I fix this ?

Your code will be much simpler, more reliable, and much more efficient if you just use indexing into one variable instead of trying to create lots of separate variables.

I'm not sure why this got resurrected more than three years later, but I guess I might as well put an answer on it, for future searchers.
To the best of my knowledge, it is not possible to dynamically create variable names in Matlab. Ultimately this is a good thing though, because Stephen's comment is correct that the code will be better if variables are indexed into arrays, rather than large groups of individually named variables. Matrices, afterall, are what Matlab was created to work with.
