✦ Synopsis

Tlic npplicntion of a modified Ramnge flamo method, employing tlic niechnnical feed derim of Stotvnrd nnd Hnrrison, to the estimation of rnrious cations line been studied, nnd working concentrntions suitnblo for routine annlysis linre been determined. The factors which may ennso inncctirncies nro discussed and tho rnotliod is c o i n p n d with tlint of LuntlcgXrdh. ltcsults for tho doterminntion of cnsily soluble soil-potnssium by both ntetltods nro quoted. Approximately cqiinl nccurncy was obtnincd from duplicntes by tho Luntlegkrdh mctliod ond quadruplicates by the mollified Rninnge mothod. It is pointed out t h t in tho pliotoiuetric evnluntion of flnnio spectrogrnms, tho use of tho rntio rntlicr tlinn tho difference of ntensurements of lino and background densities is prefernble.

Finding the general solution of a singular system of linear equations requires computing a particular solution and a basis of the null space of the corresponding singular matrix. In this paper, we consider the case where the singular matrix is large and sparse, and the application calls for a direct
