In this example, the TeLiTab is addressed in the Dataslot. The function y is defined as y = DIFF(1, 2, "XC", "YC", x, 1) With the following Telitab set in the Data slot:
|DIFF1|
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|
For x = 2.5, the function returns
...
DataSet2# = TEXTITEM$(1)
With in its dataslot:
TEXTITEM1= |0
3 "X" "Y" "Z"
"1" 1 1 2
"2" 1 4 8
"3" 1 9 18
"4" 1 16 32
"5" 1 25 50
"6" 1 36 72
"7" 1 49 98
"8" 1 64 128
"9" 1 81 162
"10" 1 100 200
"11" 2 1 12
"12" 2 4 18
"13" 2 9 118
"14" 2 16 132
"15" 2 25 150
"16" 2 36 172
"17" 2 49 198
"18" 2 64 1128
"19" 2 81 1162
"20" 2 100 1200
"21" 3 1 22
"22" 3 4 28
"23" 3 9 218
"24" 3 16 232
"25" 3 25 250
"26" 3 36 272
"27" 3 49 298
"28" 3 64 2128
"29" 3 81 2162
"30" 3 100 2200|
And use the following relation to determine the derivative:
...
With Input_Value_x = 1, Input_Value_y = 2 and OptionalDirivNo = 2 this gives Calculated_Value=2
