Inverse Box-Cox transformation
data = boxcoxinverse(transdat,lambda)
a m-by-1 matrix of doubles, the transformed data
a m-by-1 matrix of doubles, the lambda parameter
a m-by-1 matrix of doubles, greater or equal to zero, the data
boxcoxinverse applies the inverse Box-Cox transformation.
The inverse Box-Cox transformation is defined by
if lambda is nonzero and
if lambda=0.
Uses a robust implementation which is accurate even when lambda is close to zero.
Transformed data points for which the inverse does not exist (i.e. when lambda*y+1<0 ) generate NAN floating point numbers.
