EXAMPLE
In the below example, a signal of constant value of 1 is given as input to the function cumsum. The sampling frequency is set at 20000 samples/second. Thus, in a duration of 0.1 second, there will be 2000 sample points. Thus, output of the function is the sum of 1 over each sampling period. At the end of 0.1 second, the output value will be 2000.
