imbricated loops

[Delphine Fitzenz]

Hi!

It seems basic, but can-t find the reason for the bug in the FAQ or the manual.

Here goes:

EQ1, L1 and L2 are vectors of length 1000.

when I type 

EQ1(1)=0;

k=0;

for i=2:1000

for (j=1:i-1)

for (k=i+1:1000)

EQ1(i)+=L1(j)*L2(k)/(k-j);

endfor

endfor

 endfor

I get an error message at the 2nd for statement.

I tried another way, with a while loop, and then I get troubles before the second while (the equivalent of the 3rd for) when I need to initiate k to i.

It seems that octave does not want to evaluate the value of the counters. 

example:

octave-3.2.3:46> k=0;

octave-3.2.3:47> for i=2:1000

> j=1;

> while (j<i)

> k=i;

Thanks for any suggestion. I am used to programming in C or C++ and thought that just for a quick verification of a computation I could do it directly with octave, but it does not seem that straightforward...

All the best,

Delphine.
