Webb18 feb. 2016 · You are dividing by 2 then multiplying by n which is incorrect. You simply have to surround the 2*n operation with brackets: D (u+1,x+1)=au*cos ( ( (2*x+1)*u*pi)/ (2*n)); Once you do this, we get the correct DCT matrix.

WebbFör att skriva om en summa av en sinus- och cosinusfunktion som en enda sinusfunktion använder vi sambanden c=sqrt ( (a^2+b^2)) och tan (v)=b/a. För funktionen y=4sin (x) +3cos (x) är a=4 och b=3. Vi börjar med att bestämma c, dvs. amplituden för den nya sinusfunktionen.
