Matlab code for computing the co-spectra of wave perturbations (see my thesis (Pages 54-56))

• space_time_Hayashi.m: subroutine to compute the co-spectra using the method described in Hayashi (1971)
• space_time_fft2.m: subroutine to compute the co-spectra using matlab’s fft2
• test_space_time.m: sample script to run the space-time co-spectra code with idealized wave perturbations
