It has been shown recently that EI methods can be more accurate than FFT methods (Courtney and Courtney, A More Accurate Fourier Transform ) for scientific data analysis and that EI methods can be implemented. In 1959 the international yard and pound agreement (between the United States and countries of the Commonwealth of Nations) defined a yard as being exactly 0. By 2007, this had diminished to less than 0. Using FFT to calculate DFT reduces the complexity from O (N^2) to O (NlogN) which is great achievement and reduces complexity in greater amount for the large value of N. This is why cos shows up blue and sin shows up green. If this approach resonates with you, welcome aboard. And it's this -- when that hit -- when that possibility hit, it made a big difference. However matrices can be not only two-dimensional, but also one-dimensional (vectors), so that you can multiply vectors, vector by matrix and vice versa.
