I am needing to find the Fourier Transform of the following symbolic expression:
syms U(x,y,z) beta k
LHS = laplacian(U) + beta.^2*U
LHS_FT = fourier(LHS)
I'm needing to take the spatial 3D Fourier Transform of LHS.
This is the output I get:
LHS(x, y, z) =
LHS_FT(y, z) =
I am stuck here, any help would be much appreciated! Thank you in advance!
