Description Find the position of the minimum value in an array.
Arguments and Return Values Arguments: A numeric array Return Value: A 3x1x1 INT array containing the [x,y,z] position of the minimum value
Usage Syntax: minpos(data=VAL[, iter=INT][, ignore=VAL][, gt=VAL][, showval=INT]) 'data' - Any numeric array 'iter' - Number of lowest values desired 'ignore' - The value to ignore while searching for maximum value. 'gt' - Search for a minimum value above this 'greater than' value. 'showval' - Optional flag to return a 4xNx1 FLOAT array containing the value of the element.
Examples dv> a 345x500x10 array of float, bsq format [6,900,000 bytes] dv> minpos(a) 3x1x1 array of int, bsq format [12 bytes] 1 1 1 dv> minpos(a,gt=2) 3x1x1 array of int, bsq format [12 bytes] 3 1 1 dv> minpos(a,iter=2) 3x2x1 array of int, bsq format [24 bytes] 1 1 1 1 2 2 |
