This chop provides more complicated math functions than found in the Math chop: trigonometic functions, logarithmic functions and exponential functions. Since many of these functions can produce math errors, an error handling tab is provided for error handling and recovery.
Most of the functions require only one parameter, and they are applied as a unary operator to each input channel. Some functions take two parameters, and these require the use of the second input. The first parameter, X, is always a value from a channel in the first input. The second parameter, Y, is a value from a corresponding channel in the second input. Channels from each input are paired by name or index.
Errors can be handled by replacing the bad sample with a pre-defined value or by using the value of the previous sample. Alternatively, cooking can be aborted upon error for debugging networks.
Parameters
Function
Function | Which math function to apply to the channels. All of the functions are unary functions except for the binary functions 'Arctan (Input1/Input2)' and 'Input1 ^ Input2'. |
Base Value | The value of the base for 'Log base N' and 'Base ^ Input1'. |
Exponent Value | The value of the exponent for 'Input1 ^ Exponent'. |
Angle Units | For trigonometric functions, the angles can be measured in Degrees, Radians, or Cycles (0 to 1). |
Match By | How to pair channels together from the two inputs for the binary functions, by name or by channel index. |
Error
Error Handling | How to correct samples with math errors.
| ||||||
Plus Infinity Value | Value to use when an infinity error occurs. Caused by sinh(), cosh() and tan(). | ||||||
Minus Infinity Value | Value to use when a negative infinity error occurs. Caused by sinh() and tan(). | ||||||
Domain Error Value | Value to use when the input is out of the legal range of the function. Caused by asin(), acos(), log10(), logN(), ln() and sqrt(). | ||||||
Divide Error Value | Value to use when a divide by zero error occurs. Caused by pow(x,y). |
