Package dawson (in dawson.i) -

Index of documented functions or symbols:


DOCUMENT any_in(left,x,right, mask, xx, a,aa, b,bb, c,cc
  return the number of elements of the array X which are in the
  interval LEFT < X <= RIGHT.  Also return MASK, which has the
  shape of X and is 1 where X is in the interval and 0 otherwise,
  and XX = X(where(MASK)).  Up to three optional arrays A, B, and C
  of the same shape as X may be supplied; the arrays AA, BB, and CC
  analogous to XX are returned.  LEFT or RIGHT may be [] for the
  interval to extend to infinity on the corresponding side.
  LEFT and/or RIGHT may be arrays as long as they are conformable
  with X.

DOCUMENT dawson(x)
  return Dawson's integral, exp(-x^2)*integral[0 to x](exp(t^2)*dt)
  maximum is dawson(0.9241388730) = 0.5410442246
  inflection point is dawson(1.5019752682) = 0.4276866160

SEE ALSO: erf, erfc


  return erf(x), 2./sqrt(pi) * integral[0 to x](exp(-t^2)*dt)

SEE ALSO: erfc, dawson


DOCUMENT erfc(x)
  return erfc(x), 2./sqrt(pi) * integral[x to infinity](exp(-t^2)*dt)

SEE ALSO: erf, dawson


DOCUMENT merge_n(val1,mask1, val2,mask2, ...)
  return array with shape of MASKi (which must all have same shape)
  and values VALi where MASKi is true.  Unspecified values will be
  zero; the data type of the result is the data type of the first
  non-nil VALi.  Each VALi must be a 1D array of length sum(MASKi!=0).
