Write an M-file called syn_sin.m that will synthesize a waveform in the form of (7). Although for loops are rather inefficient in MATLAB, you must write the function with one loop in this lab.

Xk (1) corresponds to frequency fk (1), Xk (2) corresponds to frequency fk (2), etc. The MATLAB syntax length (fk) returns the number of elements in the vector fk, so we do not need a separate input argument for the number of frequencies. On the other hand, the programmer (that's you) should provide error checking to make sure that the lengths of fk and Xk are the same. See help error. Finally, notice that the input fs defines the number of samples per second for the cosine generation; in other words, we are no longer constrained to using 20 samples per period.
