MEAN returns the mean or averaged value of a data set

Syntax

1. MEAN(Pno%, Ndim%, "ColLab$_1",.., "ColLab$_Ndim%")
2. MEAN(0, Npoints%, x_1, y_1, x_2, y_2,...)
3. MEAN(@ObjFn(..), Ndim%, @ObjColPar_1,.., @ObjColPar_Ndim%)
4. MEAN(Telitab$, Ndim%, "ColLab$_1",.., "ColLab$_Ndim%")

...

1. See also Telitab access for a generic description on the use of TeLiTab data
2. Similar to other Data analysis functions, the MEAN is a convenient way to evaluate data. Please also look at these functions for syntax examples
3. For a multi-dimensional dataset the MEAN will be determined over all columns. This means that all defined values will be added and divided by the total number of values in the selected columns 

...

In this example syntax 1 is used, the TeLiTab is addressed in the Dataslot.

Let y be defined by

y = MEAN(1, 2, "XC", "YC")

And the data slot of the relation contains the folllowing Telitab set:

|MEAN1| 
0 
2 "XC" "YC" 
"1" 1 1 
"2" 2 4 
"3" 3 9 
"4" 4 16 
"5" 5 25 
"6" 6 36 
"7" 7 49 
"8" 8 64 
"9" 9 81 
"10" 10 100|

...

• If you apply the symbolic addressing of the columns for the description of the point on the curve or surface to compute the differential for, e.g. "Par_x" and "Par_y", please make sure that your Telitab set contains these names. If not, an error message is generated and the calculation is stopped.
• If you use |1| as data header instead of |MEAN1| it means that any special function in that expression referring to a data set Pno%=1 can access that data set.

...

In direct definition, the values are stated in the Relation itself. This method can only be used for 2D derivatives

The syntax is 

MEAN( Pno%, Npoints%, x_1, x_2,.., x_n)

If Pno%=0 then all x_i values should be numerical expressions. The minimum number of values in the list is 2.

Let y be defined by

y = MEAN(0, 4, 1, 2, 4, 9)

This Equation results in y=4.
