Summation
The Summation() function adds the body results over all i values. The syntax is:
Summation( initialization, limitvalue, body );
For example:
s = Summation( i = 1, 10, i );
returns 55, the result of 1+2+3+4+5+6+7+8+9+10.
The script works like this:
|
s = |
Sets the s variable to the value of the function. |
|
Summation( |
Begins the Summation() loop. |
|
i = 1, |
Sets i to 1. |
|
10, |
Sets the limit of i to 10. |
|
i |
All values of i from 1 to 10 are added together, resulting in 55. |
|
); |
Ends the loop. |
This behavior is similar to Σ in the Formula Editor. The following expression:
Summation( i = 1, N Row(), x ^ 2 );
is equivalent to the following formula in the Formula Editor:
