/**
* Equilibrates a real symmetric matrix `A` stored in packed format using scaling factors `S`.
*
* @param {string} order - storage layout
* @param {string} uplo - specifies whether the upper or lower triangular part of the symmetric matrix `A` is stored
* @param {NonNegativeInteger} N - order of matrix `A`
* @param {Float64Array} AP - packed symmetric matrix `A`
* @param {Float64Array} S - scale factors vector
* @param {number} scond - ratio of smallest `S[i]` to largest `S[i]`
* @param {number} amax - absolute value of largest matrix entry
* @throws {TypeError} first argument must be a valid order
* @throws {TypeError} second argument must specify whether the lower or upper triangular matrix is supplied
* @throws {RangeError} third argument must be a nonnegative integer
* @returns {string} character flag indicating whether the matrix was equilibrated ('Y') or not ('N')
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
* var dlaqsp = require( '@stdlib/lapack/base/dlaqsp' );
*
* var AP = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
* var S = new Float64Array( [ 0.05, 2.0, 4.0 ] );
*
* var out = dlaqsp( 'column-major', 'upper', 3, AP, S, 0.0125, 6.0 );
* // returns 'Y'
