...
Returns the vector (minimum) value of all the values of the vector. Only non-missing values are considered in the calculation. If there are no valid values, the function returns the missing value indicator.
number mean( vector )
Returns the mean of all non-missing values in the input vector. If there are no valid input values, then nil is returned.
vector merge( vector,vector,... )
...
Returns the vector of the square root of the input vector at each element. Missing values are retained, unaltered by the calculation.
number sum( vector )
Returns the sum of all non-missing values in the input vector. If there are no valid input values, then nil is returned.
vector tan( vector )
Return the tangent of the input vector at each element. Input vector must have values in radians. Missing values are retained, unaltered by the calculation.
