The Poisson solvers in polar and cylindrical coordinate systems are developed using Fourier-Chebyshev collocation spectral method based on matrix-matrix multiplication.

According to fifteen sorts of eigenvalues,the specific solution to a type of homogeneous equation with harmonic operator of six steps polynomial in cylindrical coordinate is obtained by the variable method, and the method of determining the constant is given.
