is (row) x (matrix) x (col) so it is also a scalar. Now that R*R' is out front, one can pull out G*G' and all that is left is T*T', which is the outer product (col) x (row). It's a matrix of rank 1. All together you have 테마복사 (T*T')*(R*R')* ...

the potential with the centrifugal barrier included, is real and that only a single generalized classical turning point exists, we derive, on the basis of a phase-integral method, a new, general formula for the calculation of such matrix elements without the use of wavefunctions. The formula ...

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...
Elliptic Integral for Matrix Input Call ellipticK for this symbolic matrix. When the input argument is a matrix, ellipticK computes the complete elliptic integral of the first kind for each element. ellipticK(sym([-2*pi -4; 0 1])) ans = [ ellipticK(-2*pi), ellipticK(-4)] [ pi/2, ...
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 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...
