After splitting $2 in an array, I am trying to store the number of unique elements in a variable, but have some difficulties resetting the variable to 0 before processing a new record.
I tried several variants of the following code, but it only works for the first record (all other record take into account the occurrence of the previous line(s)).

I am attempting to write a awk script that reads in a file after awk array elements are assigned and using those elements while reading in the new file. Does this make sense?

Hi all,
I want to write a awk script that counts unique IPs that have received one special error.
For example

Can you search AWK array elements and return each index value for that element.
For example an array named car would have index make and element engine. I want to return all makes with engine size 1.6.
Array woulld look like this:
BMW 1.6
BMW 2.0
BMW 2.5
AUDI 1.8
AUDI 1.6

This question is for someone that's more familiar with Array Element.
I need to know if the maximum array element that can be assigned is 1024 and if its so, Is there a workaround solution when the counter exceeded 1024?

counter=$counter+1

Hello,
I want to see if element exists in array, if so then, check it's corresponding value.
Column 4 is position and column 1 is the chromosome for it. There are duplicates for one position on one chromosome.
I want to check if same position exists on different chromosome:

What is an efficient way of counting the number of unique values in a 400 column by 1000 row array and outputting the counts per column, assuming the unique values in the array are:
A, B, C, D
In other words the output should look like: Value COL1 COL2 COL3
A 50 51 52... (16 Replies)
Hi,
Sure it's an easy one, but it drives me insane.
input ("|" separated):
1|A,B,C,A
2|A,D,D
3|A,B,B
I would like to count the occurence of each capital letters in $2 across the entire file, knowing that duplicates in each record count as 1.
I am trying to get this output... (5 Replies)

DLAGTS(l) ) DLAGTS(l)
NAME
DLAGTS - may be used to solve one of the systems of equations (T - lambda*I)*x = y or (T - lambda*I)'*x = y,
SYNOPSIS
SUBROUTINE DLAGTS( JOB, N, A, B, C, D, IN, Y, TOL, INFO )
INTEGER INFO, JOB, N
DOUBLE PRECISION TOL
INTEGER IN( * )
DOUBLE PRECISION A( * ), B( * ), C( * ), D( * ), Y( * )
PURPOSE
DLAGTS may be used to solve one of the systems of equations (T - lambda*I)*x = y or (T - lambda*I)'*x = y, where T is an n by n tridiagonal
matrix, for x, following the factorization of (T - lambda*I) as
(T - lambda*I) = P*L*U ,
by routine DLAGTF. The choice of equation to be solved is controlled by the argument JOB, and in each case there is an option to perturb
zero or very small diagonal elements of U, this option being intended for use in applications such as inverse iteration.
ARGUMENTS
JOB (input) INTEGER
Specifies the job to be performed by DLAGTS as follows:
= 1: The equations (T - lambda*I)x = y are to be solved, but diagonal elements of U are not to be perturbed. = -1: The equa-
tions (T - lambda*I)x = y are to be solved and, if overflow would otherwise occur, the diagonal elements of U are to be per-
turbed. See argument TOL below. = 2: The equations (T - lambda*I)'x = y are to be solved, but diagonal elements of U are not to
be perturbed. = -2: The equations (T - lambda*I)'x = y are to be solved and, if overflow would otherwise occur, the diagonal
elements of U are to be perturbed. See argument TOL below.
N (input) INTEGER
The order of the matrix T.
A (input) DOUBLE PRECISION array, dimension (N)
On entry, A must contain the diagonal elements of U as returned from DLAGTF.
B (input) DOUBLE PRECISION array, dimension (N-1)
On entry, B must contain the first super-diagonal elements of U as returned from DLAGTF.
C (input) DOUBLE PRECISION array, dimension (N-1)
On entry, C must contain the sub-diagonal elements of L as returned from DLAGTF.
D (input) DOUBLE PRECISION array, dimension (N-2)
On entry, D must contain the second super-diagonal elements of U as returned from DLAGTF.
IN (input) INTEGER array, dimension (N)
On entry, IN must contain details of the matrix P as returned from DLAGTF.
Y (input/output) DOUBLE PRECISION array, dimension (N)
On entry, the right hand side vector y. On exit, Y is overwritten by the solution vector x.
TOL (input/output) DOUBLE PRECISION
On entry, with JOB .lt. 0, TOL should be the minimum perturbation to be made to very small diagonal elements of U. TOL should
normally be chosen as about eps*norm(U), where eps is the relative machine precision, but if TOL is supplied as non-positive, then
it is reset to eps*max( abs( u(i,j) ) ). If JOB .gt. 0 then TOL is not referenced.
On exit, TOL is changed as described above, only if TOL is non-positive on entry. Otherwise TOL is unchanged.
INFO (output) INTEGER
= 0 : successful exit
element of the solution vector x. This can only occur when JOB is supplied as positive and either means that a diagonal element of
U is very small, or that the elements of the right-hand side vector y are very large.
