MATLAB: Average and standard deviation of one column of a matrix

Question

I want to calcualte the average and standard deviation for one column of a 1000×10 matrix.

Is there a quicker/efficient way or should I use existing code :

theSum = 0;
for k = 1 : length(x)
  theSum = theSum + x(k);
end
theMean = theSum / length(x);

Answer 1

See

• std - Standard deviation
• mean - Average or mean value of array
