hi era,
i found the problem.
the division by zeor error is happening
if the first row - "Event" is NOT equal to "A" , this is after sorting.
also you get an error if there are any blank lines at the end of the file.
any suggestion on how solve this.
thanks

I want to know how to trim a row
so lets say I have a file that looks like this:

Also, how would I bin column 2
Lets so I want to add and average... (1 Reply)

I have a requirement where I have multiple flat file sources.
I need to create sample data from each source.
Example:
Source 1 has 10 flat files--
member, transaction,item,email,....etc
Now if I get any 10 records (say first 10 records) from the member flat file, I need to find those matching... (2 Replies)

Hi I have a file that I want to bin.
I am using this code:
awk -F'\t' -v r=40 '{for(i=r;i<=NF;i+=r){for(j=0;j<r;j++){sum+=$(i-j)}printf "%s ", sum/r;sum=0}; printf "\n"}' file1 > file2
So basically what this code does is that it will averaging every 40 columns (creating bins of 40). But... (2 Replies)

The format is

sgetf2
SGETF2(l) ) SGETF2(l)
NAME
SGETF2 - compute an LU factorization of a general m-by-n matrix A using partial pivoting with row interchanges
SYNOPSIS
SUBROUTINE SGETF2( M, N, A, LDA, IPIV, INFO )
INTEGER INFO, LDA, M, N
INTEGER IPIV( * )
REAL A( LDA, * )
PURPOSE
SGETF2 computes an LU factorization of a general m-by-n matrix A using partial pivoting with row interchanges. The factorization has the
form
A = P * L * U
where P is a permutation matrix, L is lower triangular with unit diagonal elements (lower trapezoidal if m > n), and U is upper triangular
(upper trapezoidal if m < n).
This is the right-looking Level 2 BLAS version of the algorithm.
ARGUMENTS
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
A (input/output) REAL array, dimension (LDA,N)
On entry, the m by n matrix to be factored. On exit, the factors L and U from the factorization A = P*L*U; the unit diagonal ele-
ments of L are not stored.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
IPIV (output) INTEGER array, dimension (min(M,N))
The pivot indices; for 1 <= i <= min(M,N), row i of the matrix was interchanged with row IPIV(i).
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -k, the k-th argument had an illegal value
> 0: if INFO = k, U(k,k) is exactly zero. The factorization has been completed, but the factor U is exactly singular, and division
by zero will occur if it is used to solve a system of equations.
