hicd

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).
  • 0 = off (default)
  • 1 = on

Example

x = c1.x
y = hicd(c1.x, c1.y, 15)
