Returns the index of largest value of argument x.
- Usage
imax(x)- Result
- The result is the index of the maximum 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 maximum
- if x is a matrix: the result is the element index i of the maximum; the column c and the row r can be computed as follows:
c := int i/x[!nrow],r := int i%x[!nrow]
