Definition of integrand in English:

integrand

noun ˈɪntɪɡrandˈin(t)əɡrənd

Mathematics

A function that is to be integrated.
〔数〕被积函数
Example sentencesExamples
- Because of the nature of the integrand, it may represent any spectral variable (frequency, wavelength, wave number or energy).
- From this point of view a curve or a surface can be identified with a linear functional over the class of variational integrands.
- Importance sampling involves evaluating the integrand at independently sampled realizations from a probability distribution that is roughly proportional to the integrand.
- It assumes an invariant average wavelength in the denominator of the integrand.
- The approximation of the integral is most accurate if the lattice points lie in the high-density region of the integrand.
Synonyms
component, constituent, part, section, portion, piece, segment, bit

Origin

Late 19th century: from Latin integrandus, gerundive of integrare (see integrate).
