Definition of integrand in English:



  • A function that is to be integrated.

    ‘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.’
    • ‘Because of the nature of the integrand, it may represent any spectral variable (frequency, wavelength, wave number or energy).’
