The fourier domain is just a linear transform of the time domain, i.e. just a matrix multiply away!

Could you expand please? I'm connecting the two via convolution but can't intuitively grasp the link yet.

See “Laplace transform”

The fourier transform converts between time domain and frequency domain. The fourier transform is linear, which means it can be implemented as multiplying your time domain signal by a matrix of complex fourier coefficients. Usually we dont do it this way because the fft is faster than matrix multplication, but the result is the same.
