Math Transforms

Absolute Value

Outputs the absolute value of the input.

Add/Subtract

Outputs the sum of all input signals.  

To subtract, use the Port Properties to change a port type to Subtract. The input value of that port is multiplied by -1, then added to the other port values, effectively performing a subtraction.

Constant

Outputs a constant value specified in its properties.

Divide

Outputs numerator divided by denominator.

Inverse Scale & Offset

Output = (Input - Offset) / Scale
 
This is the inverse of the Scale & Offset transform.  Scale and Offset values are specified in its properties.  

Invert

Performs a logical inversion. Input of 0 produces an output of 1.  Input of 1 produces an output of 0.

Min/Max

Min = the smallest of the input signals.  Max = the greatest of the input signals.

Multiply/Divide

Out = the product of the input signals. To divide, use the Transform->Edit Ports command or the Port Properties to change the port type to Divide.

Scale & Offset

Output = (Input x Scale) + Offset
 
Scale and Offset values are specified in the Transform's properties.
