Compute log(1+x) accurately for small values of x
y = log1p(x)
y = log1p(x) computes
compensating for the roundoff in
more accurate than
log(1+x) for small values of
x. For small
Calculate with arrays that have more rows than fit in memory.
This function fully supports tall arrays. For more information, see Tall Arrays.
