output =
ComputeGammaPow(x,input)
Compute the gamma table using simple gamma function.
Largest value in input must be the maximum device
setting. This is wise during measurements in
any case.
output = ((input/maxInput).^x(1));
10/3/93 dhb,jms Normalize output to max of 1, remove old x(1).
Better be sure that last value is max setting.
8/7/00 dhb Modify convention with gamma to be consistent
with extended gamma function.
Get rid of explicity normalization.
