Min( <List> )
Returns the minimum of the numbers within the list.
Example: Min({-2, 12, -23, 17, 15}) yields -23.
Note: If the input consists of non-numeric objects, then this command considers the numbers associated with those objects. If you have a list of segments for example, the command Min( <List> ) will yield the minimum segment length.
Min( <Interval> )
Returns the lower bound of the interval.
Example: Min(2 < x < 3) yields 2 .
Note: Open and closed intervals are not distinguished.
Min( <Number>, <Number> )
Returns the minimum of the two given numbers.
Example: Min(12, 15) yields 12.
Min( <Function>, <Start x-Value>, <End x-Value> )
Calculates (numerically) the local minimum point for function in the given interval. Function should be continuous and have only one local minimum point in the interval.
Note: For polynomials you should use the Extremum Command.
Example: Min(exp(x) x^3,-4,-2) creates the point (-3, -1.34425) .
Min( <List of Data>, <List of Frequencies> )
Returns the minimum of the list of data with corresponding frequencies.
Example: Min({1, 2, 3, 4, 5}, {0, 3, 4, 2, 3}) yields 2, the lowest number of the first list whose frequency is greater than 0.
