IDAMAXRun Method

***PURPOSE Find the smallest index of that component of a vector having the maximum magnitude. ***CATEGORY D1A2 ***TYPE DOUBLE PRECISION (ISAMAX-S, IDAMAX-D, ICAMAX-C) ***KEYWORDS BLAS, LINEAR ALGEBRA, MAXIMUM COMPONENT, VECTOR ***AUTHOR Lawson, C. L., (JPL) Hanson, R. J., (SNLA) Kincaid, D. R., (U. of Texas) Krogh, F. T., (JPL) ***DESCRIPTION B L A S Subprogram Description of Parameters --Input-- N number of elements in input vector(s) DX double precision vector with N elements INCX storage spacing between elements of DX --Output-- IDAMAX smallest index (zero if N .LE. 0) Find smallest index of maximum magnitude of double precision DX. IDAMAX = first I, I = 1 to N, to maximize ABS(DX(IX+(I-1)*INCX)), where IX = 1 if INCX .GE. 0, else IX = 1+(1-N)*INCX. ***REFERENCES C. L. Lawson, R. J. Hanson, D. R. Kincaid and F. T.
