Multiplying two variables in a table together

How would you multiply two variables/columns together from a table together, to create a new variable/column?

Lets say for example you have the following table:

Time Voltage Current

_____ _____ _____

1 8 2

2 9 4

3 6 6

And you want to multiply voltage and current together at each sample.

So you'd end up with a 4th column/variable called power that is voltage multiplied by current at each time interval

T.Power = T.Voltage.*T.Current;

where T is your table.

Running your example:

Time = [1;2;3];
Voltage = [8;9;6];
Current = [2;4;6];
T = table(Time,Voltage,Current)

T = 3×3 table
    Time    Voltage    Current
    ____    _______    _______

     1         8          2   
     2         9          4   
     3         6          6   

T.Power = T.Voltage.*T.Current

T = 3×4 table
    Time    Voltage    Current    Power
    ____    _______    _______    _____

     1         8          2        16  
     2         9          4        36  
     3         6          6        36
