Calculate the power using the current values inside matrix

how do you work out a loop to calculate power when you have been give the current ( a 6*6)matrix. and your answer in a matrix form should have 36 members annd you are supposed to have 6 loop sentences to calculate the 36 values?

[Fangjun Jiang]

Do you need the voltage to calculate the power from current?

[Walter Roberson]

Is the current a 6*6 matrix as in your question, or a 6*1 matrix as in your Tags ?

Answer 1

[Walter Roberson]

For the case where they are 6 x 1, something like:

bsxfun(@times, current(:), voltage(:).')

Answer 2

[Fangjun Jiang]

Voltage=1:6;
Current=0.1:0.1:0.6;
Power=zeros(6,6);
for k=1:6
  for j=1:6
     Power(k,j)=Voltage(k)*Current(j);
  end
end
