Parameters |
Description |
|
double dParam |
[in] A parameter to be evaluated. |
Evaluates the parameter using the following formula: Output = atan( ( amplitude * cos( ( param * frequency) + phase) ) ) * a and returns its value. The following condition should be verified: –263 < (param * frequency) + phase < 263.
