This is the problem: Generate a new vector called voltage_distorted and set it equal to vector voltage (I have the data for this). Now modify voltage_distorted such that all voltage values greater than 0 are multiplied by 2, and all values that are less than or equal to 0 are divided by 2.

for example:
voltage = [3 -6 -2 4 1];
voltage_distorted = voltage;
voltage_distorted(voltage_distorted>0) = voltage_distorted(voltage_distorted>0)*2;
voltage_distorted(voltage_distorted<=0) = voltage_distorted(voltage_distorted<=0)/2;
The answer will be:
voltage_distorted = [6 -3 -1 8 2]
