However, the definition of the MATLAB sinc function is slightly different than the one used in class and on the Fourier transform table. If a function is periodic and follows below 2 conditions, then the Fourier series for such a function exists. Signal Generation and Visualization - MATLAB & Simulink ... end. But It should be periodic within all time. for a=0:n-1 %the use of the for can be avoided somehow. The function Mod[x, 2*L, -L] (1) adds L to x, (2) calculates the remainder on dividing (1) by 2*L, (3) subtracts L from (2).This has the effect of shifting the original x by ±2L until it falls into the range [-L,L). %xxx=xxx-floor (n/2); %just in case you want to shift the x values. Create a script file and type the following code −. The first case seems to be easier and reasonable since we do not have to "redefine" trig functions and can convert them into the . Second , your 'f' calculation is vectorised at each iteration, producing a (1x10001) row vector. John Nosh on 3 Sep 2017. Are you saying you want an infinite number of function values stored on your computer? F (x)=Sin (t) --> pi/3 <t<2*pi/3.
