WebSep 26, 2015 · A purely real, even (or "symmetric") function has a Fourier transform function that is also real and even. "Even" is the symmetry with respect to the y-axis, or the t=0 line. When implementing a signal in Matlab, however, you always start from t=0. WebHistorically, the introduction of complex numbers was primarily associated with the idea of solving equations. In particular, in the 16th century, mathematicians were working to find algebraic solutions to the cubic equation. Intriguingly, the equations mathematicians were trying to solve often had purely real solutions.
