Returns the index of smallest value of argument x.

Usage

imin(x)

Result

The result is the index of the minimum value of x.

if x is a scalar: the result is 0
if x is a vector: the result is the index (row) of the minimum
if x is a matrix: the result is the element index i of the minimum; the column c and the row r can be computed as follows: c := int i/x[!nrow], r := int i%x[!nrow]
