rowImin

Syntax

rowImin(args...)

Please see rowFunctions for the parameters and calculation rules.

Details

Return the index of the minimum in each row. If there are multiple minima, return the index of the first minimum from the left. The result is a vector with the same length as the number of input rows.

Examples

m=matrix([4.5 2.6 1.5 3.2, 1.5 4.8 5.9 1.7, 4.9 2.0 NULL 5.5])
rowImin(m)
// output
[1,2,0,1]
