WebWe know that the domain of the cosine function is R, that is, all real numbers and its range is [-1, 1]. A function f(x) has an inverse if and only if it is bijective(one-one and onto). Since cos x is not a bijective function as it is not one-one, the inverse cosine cannot have R as its range.Hence, we need to make the cosine function one-one by restricting its domain. WebDec 27, 2024 · Conveniently, there is a sinc() function built into MATLAB. But when you call fft(), if you have enough sample points in your signal, you should actually see the familiar sinc shape in the magnitude of the signal.
