To be more specific, array should be lower than 44.361416 as it comes
from the elementary
function InvFisherTfm( array )
{
e2y = exp( 2 * array );
return ( e2y - 1 )/( e2y + 1 );
}
y0=0;
for(array=44;array<45;array=array+0.00001)
{
y=InvFisherTfm(array);
if(Nz(y)!=0)
y0=array;
}
Title="Maximum Accepted Array = "+WriteVal(y0,1.6);
