Argument for the exponential function |
tLevel |
Truncation level |
Truncation can be useful in combination with basis function expansions where there is a need to store a large number of evaluations. Truncation of small values to 0 allow for efficient storage using e.g. sparse matrices.
exp(x) if exp(x) >= \code{tLevel} and 0 if exp(x) < \code{tLevel}.
