Generate a Sine Wave in which I can change the sampling rate.

i wish to generate a basic sine wave and then plot it.

i then wish to take that basic sine wave and change the sampling rate (say from 1 to 10 to 100 to 1000 sampling points).

i do not have simulink. thanks.

%asks for sample rate

   sample_rate = input('Type the sample rate:\n')

%time

   t=0:2*pi/sample_rate:2*pi;

%discrete plot

   stem(t,sin(t))

awesome, thanks so much

Anytime.

would you know how to make the plot have an x-axis of 0-7 milliseconds and the y axis to have -30 to +50 millivolts?
