Modified Head Injury Criterion for use with the free-motion head form.
        Syntax
            
            hicd(vector1, vector2,
                    scalar1, 1|2,
                [on|off])
        
        Arguments
            
            
                
                    
                        - vector1
- The time vector of data to analyze (second).
- vector2
- The head acceleration vector (g).
- scalar1
- Window in millisecond.
- 1|2
- Return vector type (optional):
- If not present or (arg4 != 1 && arg4 != 2), a single vector
                            containing the following three members:
                                - [0] = hicd value
- [1] = lower time window (milliseconds)
- [2] = upper time window (milliseconds)
 
- If 1, a single vector containing the following four members (use as X-axis):
                                - [0] = lower time window (milliseconds)
- [1] = lower time window (milliseconds)
- [2] = upper time window (milliseconds)
- [3] = upper time window (milliseconds)
 
- If 2, a single vector containing the following four members (use as Y-axis):
                                - [0] = 0.0
- [1] = hicd value
- [2] = hicd value
- [3] = 0.0
 
- 0|1
- Flag to turn on debug mode and print to the message log (optional).
 
        
        Example
            
            
                x = c1.x
y = hicd(c1.x, c1.y, 15)

                hicd = (0.75446*hic)+166.4
