Hi guys,

I'd like to connect a parameter name to a moving number, performing for example the following loop:

for i=1:10
parameter "i"
end

I want the following output :

parameter 1
parameter 2
..........
parameter 10

How I can write this in Matlab?

Thks for help!
Ciao ciao!

That depends ... what are you trying to do with this connected parameter
name and number? If you're trying to create variables named parameter1,
parameter2, parameter3, etc. then you should not do this for reasons
described in question 4.6 in the newsgroup FAQ. If you're just looking to
display those strings, use FPRINTF or SPRINTF.

for k = 1:10
fprintf('parameter %d\n', k);
end

Hi Steve,

thks for your reply!
I try to explain what really I'd like to do.
I have a big vector "A" of 1000 elements (but the dimension could be variable).
I want to create 10 new vectors of 100 elements each.
These new vectors shall have the following names:

A1 = first 100 elements of "A"
A2 = second 100 elements of "A"
and so on....

So I need an incremental number to link to the fixed part "A".

Regards
Ale

Don't do this. See Q4.6 in the newsgroup FAQ for alternatives.

Hi Steve,

in 4.6 of Matlab_FAQ I found that code:

for i=1:10
eval(sprintf('A%d = [1:i]', i));
end

and it looks interesting...thanks for the suggestion!!

Bye bye!
