PHP question...I posted this on the Web Development forum, but maybe this is a better place!
I have an SQL query that's pulled back user IDs as a set of columns. Rather than IDs, I want to use their names.
So I have an array of columns $col with values 1,7,3,12 etc and I've got an array $person... (3 Replies)
Hi all,
I wanted to access two arrays (of same size) using one for loop.
Ex:
#!/bin/bash
declare -a num
declare -a words
num=(1 2 3 4 5 6 7)
words=(one two three four five six seven)
for num in ${num}
do
echo ":$num: :${words}:"
done
Required Output:
:1: :one: (11 Replies)

Hi
I have redc containing the values 3, 6, 2, 8, and 1.
I have work containing the values 8, 2, 11, 7, and 9.
Is there a way to find the sum of redc and work?
I need to compare the sum of those two arrays to something else, so is it okay to put that into my END?
TY! (4 Replies)
Hi,
Is there a concept of lables in vi editor. In mainframes ISPF editor there is a concept of labels where one can label a line say ".a" and after that wherever you are in the file, if one want to go back to that particular line where the label was set...he could do by "l .a"....Is there... (1 Reply)
Hi All,
need help with reading the array and sum of the array elements.
given an array of integers of size N . You need to print the sum of the elements in the array, keeping in mind that some of those integers may be quite large.
Input Format
The first line of the input consists of an... (1 Reply)
I need your help to discover missing elements for each box.
In theory each box should have 4 items: ITEM01, ITEM02, ITEM08, and ITEM10.
Some boxes either have a missing item (BOX02 ITEM08) or might have da duplicate item (BOX03 ITEM02) and missing another one (BOX03 ITEM01).

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)
So I need to Write an array processing program using a Linux shell programming language to perform the following.

SYNOPSIS
Functions/Subroutines
REAL function slangt (NORM, N, DL, D, DU)
SLANGT
Function/Subroutine Documentation
REAL function slangt (characterNORM, integerN, real, dimension( * )DL, real, dimension( * )D, real, dimension( * )DU)
SLANGT
Purpose:
SLANGT returns the value of the one norm, or the Frobenius norm, or
the infinity norm, or the element of largest absolute value of a
real tridiagonal matrix A.
Returns:
SLANGT
SLANGT = ( max(abs(A(i,j))), NORM = 'M' or 'm'
(
( norm1(A), NORM = '1', 'O' or 'o'
(
( normI(A), NORM = 'I' or 'i'
(
( normF(A), NORM = 'F', 'f', 'E' or 'e'
where norm1 denotes the one norm of a matrix (maximum column sum),
normI denotes the infinity norm of a matrix (maximum row sum) and
normF denotes the Frobenius norm of a matrix (square root of sum of
squares). Note that max(abs(A(i,j))) is not a consistent matrix norm.
Parameters:
NORM
NORM is CHARACTER*1
Specifies the value to be returned in SLANGT as described
above.
N
N is INTEGER
The order of the matrix A. N >= 0. When N = 0, SLANGT is
set to zero.
DL
DL is REAL array, dimension (N-1)
The (n-1) sub-diagonal elements of A.
D
D is REAL array, dimension (N)
The diagonal elements of A.
DU
DU is REAL array, dimension (N-1)
The (n-1) super-diagonal elements of A.
