```drscl.f(3)							      LAPACK								drscl.f(3)

NAME
drscl.f -

SYNOPSIS
Functions/Subroutines
subroutine drscl (N, SA, SX, INCX)
DRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation
subroutine drscl (integerN, double precisionSA, double precision, dimension( * )SX, integerINCX)
DRSCL multiplies a vector by the reciprocal of a real scalar.

Purpose:

DRSCL multiplies an n-element real vector x by the real scalar 1/a.
This is done without overflow or underflow as long as
the final result x/a does not overflow or underflow.

Parameters:
N

N is INTEGER
The number of components of the vector x.

SA

SA is DOUBLE PRECISION
The scalar a which is used to divide each component of x.
SA must be >= 0, or the subroutine will divide by zero.

SX

SX is DOUBLE PRECISION array, dimension
(1+(N-1)*abs(INCX))
The n-element vector x.

INCX

INCX is INTEGER
The increment between successive values of the vector SX.
> 0:  SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i),	 1< i<= n

CSRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation
subroutine csrscl (integerN, realSA, complex, dimension( * )SX, integerINCX)
CSRSCL multiplies a vector by the reciprocal of a real scalar.

Purpose:

CSRSCL multiplies an n-element complex vector x by the real scalar

## Sorting a vector of strings into numerical order.

I have a vector of strings that contain a list of channels like this: 101,99,22HD,432,300HD I have tried using the sort routine like this: sort(mychans.begin(),mychans.end()); For some reason my channels are not being sorted at all. I was hoping someone might have some input that might...
