From Fr. complexe, from L. complexus "surrounding, encompassing," p.p. of complecti "to embrace, encompass, include," from → com- "together" + plectere "to weave, twine."
Hamtâft, from ham- "together," → com- + tâft past stem of tâftan, tâbidan "to twist, to spin, to bend, to crook," p.p. tâftah "spun, silk or linen cloth," loaned into E. taffeta (from O.Fr. taffetas, from It. taffeta); similarly Gk. tapetion "little carpet" is probably from this Iranian origin (from which tapestry, tapis); Proto-Ir. *tap- "to spin," related to tan-, tanidan "to spin; to stretch," → tension.

Fr.: variable dynamique complexe
complex Fourier series
seri-ye Fourier-ye hamtâft
Fr.: série de Fourier complexe
The complex notation for the → Fourier series of a function f(x). Using → Euler's formulae, the function can be written in cimplex form as f(x) = Σ cn einx (summed from -∞ to ∞), where the → Fourier coefficients are cn = (1/2π)∫ f(x) e-inx dx (integral from -π to +π).
Fr.: fraction complexe
Fr.: molécule complexe
A molecule in the → interstellar medium comprising at least six atoms (e.g. Herbst & van Dishoeck, 2009, ARA&A).
adad-e hamtâft (#)
Fr.: nombre complexe
Any number of the form u = a + bi, where a and b are → real numbers and i imaginary, i.e. i2 = -1.
