Hi all,
Is there a way to convert full data matrix to linearised left data matrix?
e.g full data matrix

is it possible to count the number of keys based on state and cell and output it as a simple matrix.
Ex: cell1-state1 has 2 keys
cell3-state1 has 4 keys.
Note: Insert 0 if no data available.

Hi,
Some assistance with respect to the following problem will be very helpful.
I want to reformat my dataset in the following manner for subsequent analysis.

thank you for letting me join this forum, lots of learning opportunities looks like.
Myself a biologist, very new into unix, so please excuse if I use incorrect language. I am using cygwin on windows, it can run perl, awk , sed etc.
I have 2 files, the first sample sheet, tells which parent... (10 Replies)

CGESV(l) ) CGESV(l)
NAME
CGESV - compute the solution to a complex system of linear equations A * X = B,
SYNOPSIS
SUBROUTINE CGESV( N, NRHS, A, LDA, IPIV, B, LDB, INFO )
INTEGER INFO, LDA, LDB, N, NRHS
INTEGER IPIV( * )
COMPLEX A( LDA, * ), B( LDB, * )
PURPOSE
CGESV computes the solution to a complex system of linear equations A * X = B, where A is an N-by-N matrix and X and B are N-by-NRHS matri-
ces.
The LU decomposition with partial pivoting and row interchanges is used to factor A as
A = P * L * U,
where P is a permutation matrix, L is unit lower triangular, and U is upper triangular. The factored form of A is then used to solve the
system of equations A * X = B.
ARGUMENTS
N (input) INTEGER
The number of linear equations, i.e., the order of the matrix A. N >= 0.
NRHS (input) INTEGER
The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
A (input/output) COMPLEX array, dimension (LDA,N)
On entry, the N-by-N coefficient matrix A. 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,N).
IPIV (output) INTEGER array, dimension (N)
The pivot indices that define the permutation matrix P; row i of the matrix was interchanged with row IPIV(i).
B (input/output) COMPLEX array, dimension (LDB,NRHS)
On entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if INFO = 0, the N-by-NRHS solution matrix X.
LDB (input) INTEGER
The leading dimension of the array B. LDB >= max(1,N).
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the
solution could not be computed.
