The main objective of this study is to find the solution of the generalized heat and generalized Laplace equations using the fractional Fourier transform, which is a general form of the solution of these equations using the classical Fourier transform. The solution is also formulated using a sampling formula related to the fractional Fourier transform. The study introduces the fractional Fourier transform, collects related theorems and essential properties, and derives several results related to the sampling formula. Several examples are presented to demonstrate the effectiveness and powerfulness of the proposed method compared to the classical Fourier transform method.
