In the secondary output:
where do these numbers come from?
If you're counting the number of times a digit appears in the input, 0 occurs 13 times (not 12 times) in your sample input. If you're counting the number of times a value appears in your sample input, 0 (or 00) does not appear at all???
All of your input values are two digit strings. Are we supposed to treat 01 and 1 as the same value or as distinct values? If they are the same, is 010 to be treated as an octal value (decimal 8) or as a decimal value (10)?
Hi Guys...
I am newbie to awk and would like a solution to probably one of the simple practical questions.
I have a test file that goes as:
1,2,3,4,5,6
7,2,3,8,7,6
9,3,5,6,7,3
8,3,1,1,1,1
4,4,2,2,2,2
I would like to know how AWK can get me the distinct values say for eg: on col2... (22 Replies)
Hello,
I have a 1.6 GB file that I would like to modify by matching some ids in col1 with the ids in col 1 of file2.txt and save the results into a 3rd file.
For example:
File 1 has 1411 rows, I ignore how many columns it has (thousands)
File 2 has 311 rows, 1 column
Would like to... (7 Replies)
Hello everyone,
I am writing a script to process data from the ATP world tour.
I have a file which contains:

I am a new user of Unix/Linux, so this question might be a bit simple!
I am trying to join two (very large) files that both have different # of cols and rows in each file.
I want to keep 'all' rows and 'all' cols from both files in the joint file, and the primary key variables are in the rows.... (1 Reply)
Hi,
Please help with this.
I have several excel files (with and .xlsx format) with 10-15 columns each.
They all have the same type of data but the columns are not ordered in the same way.
Here is a 3 column example. What I want to do add the alphabet

Hi Gurus,
I have requirement to identify the records based on one column value.
the sample file as below:

SLALSD(l) ) SLALSD(l)
NAME
SLALSD - use the singular value decomposition of A to solve the least squares problem of finding X to minimize the Euclidean norm of each
column of A*X-B, where A is N-by-N upper bidiagonal, and X and B are N-by-NRHS
SYNOPSIS
SUBROUTINE SLALSD( UPLO, SMLSIZ, N, NRHS, D, E, B, LDB, RCOND, RANK, WORK, IWORK, INFO )
CHARACTER UPLO
INTEGER INFO, LDB, N, NRHS, RANK, SMLSIZ
REAL RCOND
INTEGER IWORK( * )
REAL B( LDB, * ), D( * ), E( * ), WORK( * )
PURPOSE
SLALSD uses the singular value decomposition of A to solve the least squares problem of finding X to minimize the Euclidean norm of each
column of A*X-B, where A is N-by-N upper bidiagonal, and X and B are N-by-NRHS. The solution X overwrites B. The singular values of A
smaller than RCOND times the largest singular value are treated as zero in solving the least squares problem; in this case a minimum norm
solution is returned. The actual singular values are returned in D in ascending order.
This code makes very mild assumptions about floating point arithmetic. It will work on machines with a guard digit in add/subtract, or on
those binary machines without guard digits which subtract like the Cray XMP, Cray YMP, Cray C 90, or Cray 2. It could conceivably fail on
hexadecimal or decimal machines without guard digits, but we know of none.
ARGUMENTS
UPLO (input) CHARACTER*1
= 'U': D and E define an upper bidiagonal matrix.
= 'L': D and E define a lower bidiagonal matrix.
SMLSIZ (input) INTEGER The maximum size of the subproblems at the bottom of the computation tree.
N (input) INTEGER
The dimension of the bidiagonal matrix. N >= 0.
NRHS (input) INTEGER
The number of columns of B. NRHS must be at least 1.
D (input/output) REAL array, dimension (N)
On entry D contains the main diagonal of the bidiagonal matrix. On exit, if INFO = 0, D contains its singular values.
E (input) REAL array, dimension (N-1)
Contains the super-diagonal entries of the bidiagonal matrix. On exit, E has been destroyed.
B (input/output) REAL array, dimension (LDB,NRHS)
On input, B contains the right hand sides of the least squares problem. On output, B contains the solution X.
LDB (input) INTEGER
The leading dimension of B in the calling subprogram. LDB must be at least max(1,N).
RCOND (input) REAL
The singular values of A less than or equal to RCOND times the largest singular value are treated as zero in solving the least
squares problem. If RCOND is negative, machine precision is used instead. For example, if diag(S)*X=B were the least squares prob-
lem, where diag(S) is a diagonal matrix of singular values, the solution would be X(i) = B(i) / S(i) if S(i) is greater than
RCOND*max(S), and X(i) = 0 if S(i) is less than or equal to RCOND*max(S).
RANK (output) INTEGER
The number of singular values of A greater than RCOND times the largest singular value.
WORK (workspace) REAL array, dimension at least
(9*N + 2*N*SMLSIZ + 8*N*NLVL + N*NRHS + (SMLSIZ+1)**2), where NLVL = max(0, INT(log_2 (N/(SMLSIZ+1))) + 1).
IWORK (workspace) INTEGER array, dimension at least
(3*N*NLVL + 11*N)
INFO (output) INTEGER
= 0: successful exit.
< 0: if INFO = -i, the i-th argument had an illegal value.
> 0: The algorithm failed to compute an singular value while working on the submatrix lying in rows and columns INFO/(N+1) through
MOD(INFO,N+1).
