Text statistics
Hello every body
if I want to get the following statistics from a text file
1- sorted the n frequent words
2- sorted the n frequent characters
3- sorted the n frequent diagrams (tow letter together like th OR he)
4- sorted frequent n trigrams like (the OR all etc. )
5- any character that occurs before specific character or after it
for example if I want to know all the character that occurred before r and after r
so I can get 2 lists of characters occurred before r and after r .
for instance "tree"
t occurred before r
r followed e
and so on.
I Can do it in C or C++ program or java which can takes long time , but is there any command line in Unix can simply do that ?
Thanks a lot
Khaled

slamrg.f(3) LAPACK slamrg.f(3)
NAME
slamrg.f -
SYNOPSIS
Functions/Subroutines
subroutine slamrg (N1, N2, A, STRD1, STRD2, INDEX)
SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
Function/Subroutine Documentation
subroutine slamrg (integerN1, integerN2, real, dimension( * )A, integerSTRD1, integerSTRD2, integer, dimension( * )INDEX)
SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.
Purpose:
SLAMRG will create a permutation list which will merge the elements
of A (which is composed of two independently sorted sets) into a
single set which is sorted in ascending order.
Parameters:
N1
N1 is INTEGER
N2
N2 is INTEGER
These arguements contain the respective lengths of the two
sorted lists to be merged.
A
A is REAL array, dimension (N1+N2)
The first N1 elements of A contain a list of numbers which
are sorted in either ascending or descending order. Likewise
for the final N2 elements.
STRD1
STRD1 is INTEGER
STRD2
STRD2 is INTEGER
These are the strides to be taken through the array A.
Allowable strides are 1 and -1. They indicate whether a
subset of A is sorted in ascending (STRDx = 1) or descending
(STRDx = -1) order.
INDEX
INDEX is INTEGER array, dimension (N1+N2)
On exit this array will contain a permutation such that
if B( I ) = A( INDEX( I ) ) for I=1,N1+N2, then B will be
sorted in ascending order.
