LAPACK  3.10.0 LAPACK: Linear Algebra PACKage

## ◆ lsamen()

 logical function lsamen ( integer N, character*( * ) CA, character*( * ) CB )

LSAMEN

Purpose:
``` LSAMEN  tests if the first N letters of CA are the same as the
first N letters of CB, regardless of case.
LSAMEN returns .TRUE. if CA and CB are equivalent except for case
and .FALSE. otherwise.  LSAMEN also returns .FALSE. if LEN( CA )
or LEN( CB ) is less than N.```
Parameters
 [in] N ``` N is INTEGER The number of characters in CA and CB to be compared.``` [in] CA ` CA is CHARACTER*(*)` [in] CB ``` CB is CHARACTER*(*) CA and CB specify two character strings of length at least N. Only the first N characters of each string will be accessed.```
