In a special case, whenone hasand system (1.1) can be rewritten as the equation of a vibrating string in the sense of Krein [27] (1.3) Letandbe the unique solutions of (1.3) satisfying the initial conditions The function (1.4)
The paper deals with the calculation of diagonal as well as off-diagonal matrix elements between unbound states pertaining to a radial Schr枚dinger equation. For the case that the effective potential, i.e. the potential with the centrifugal barrier included, is real and that only a single ...
The essence of the above method is to calculate only the function of the angular spectrum component in the direction of the field source line for two groups of far-field interaction, so as to minimize the transfer of the far-field interaction group. In the light of the poor matrix behavior...

Integral equations (IEs) are functional equations where the indeterminate function appears under the sign of integration1. The theory of IEs has a long history in pure and applied mathematics, dating back to the 1800s, and it is thought to have started with Fourier’s theorem2. Another early...
Set this flag to true or 1 to indicate that fun is a function that accepts a scalar input and returns a vector, matrix, or N-D array output. The default value of false indicates that fun is a function that accepts a vector input and returns a vector output. Example: integral(fun,a,...
