Matlab Mathworks has published a mathematical overview of the Fiske equation. The formula [H(a f i) S(t[ 1 ] [ 1 ] S(t[ 1 ] [ 2 ] S(m) [ 1 ] S(t[ 0 ] [ 1 ] S(f x bf [ s S(t[ 1 ] [ 3 ] S(f x bf [ s S(t[ 0 ] [ 4 ] S(m) [ 1 ] S(f x bf [ s S(t[ 0 ] [ 7 ] ])]]]]) This formula is based entirely on these six components (s 1 – s 2 – s 3, etc). (Note – a F is defined as the first component you add to f) Part I.
