result = determ2(a, b, c, d)

NAME:determ2 PURPOSE: computes the determinant of n 2 by 2 arrays CATEGORY: no DO loops and better accuracy CALLING SEQUENCE: 2 cases: res = determ2(z2ds) res = determ2(z1d00,z1d01,z1d10,z1d11) INPUTS: z2ds: an 2*2*n array or z1d00,z1d01,z1d10,z1d11: the four n elements arrays defined as: z2ds[0, 0, *] = z1d00 z2ds[0, 1, *] = z1d01 z2ds[1, 0, *] = z1d10 z2ds[1, 1, *] = z1d11 OUTPUTS: n elements array, the determinent of each 2*2 arrrays EXAMPLE: a=findgen(2,2,5) print, determ2(a) FOR i=0,4 DO print, determ(a[*,*,i]) ; IDL solution MODIFICATION HISTORY:
