I want to generate a time vector tt corresponding to a range of values of t that will cover approxi- mately two cycles of a 440 Hz sinusoid. Also, I need to make sure that I have at least 25 samples per period of the sinusoidal wave.
I understand how to find the period but Im a little confused on getting exactly 25 samples per period. So far I have tt = -1/440: :1/440. I don't know what to put as the increments to get exactly 25 samples

I would use the linspace command to do this.
