if

The if function works similar to the if-element (see section 9.8 on page ). It will evalue a condition and than, depending on whether the condition result is true or false, will return the value of its first (true case) or second (false case) subfunction.

Syntax: $UF=if( Condition, UF_1, UF_2 )$

Description of the elements:

• $Condition$: The condition of the if-function as described in section 9.8 on page . If the condition is true, the value of first subfunction $UF_1$ will be returned, else, if the condition is false, the value of the second subfunction $UF_2$ will be returned.
• $UF_1$: The first subfunction of the if function.
• $UF_2$: The second subfunction of the if function.

Example:

• $if( lo(x,7), 1, sin(x) )$; will return $1$, if the variable $x$ is lower than $7$, else $sin(x)$ will be returned
