Hi,
I have an array of the form X = { P , P, P , P, A, A, A, P, P , P,
A , A, A}
P : finite value exists
A : value is zero
I would like to create a new array called Y = { P,P,P....} which has all
the non-zero entries. I will not know the number of non-zeros unless I
look into the array..
Using a simple loop, I believe this can be achieved.. but for large
amount of data, it takes time. What could be the simplest way of doing
this using A++ ?
I tried something like :
where ( X != 0)
{
RealArray Y=X
}
The non zero entries are there.. but the dimension of array Y is
obviously that of X.. with the remaining padded with zeros. Is there a
way to redimension this.. keeping in mind that we dont know the size of
Y ..
Thanks,
Dominic
