Example

Compute the COLMEAN of the following matrix:

 

a = {{1, 4, 7},
    {2, 5, 8},
    {3, 6, 9}};

 

b = colmean(a);

 

produces a row, or vector, of the following values:

 

b == {{2, 5, 8}}

 

Performing the TRANSPOSE of the above row vector produces a column vector. You can use this vector to perform vector calculations.

 

transpose(b) ==  {2,
                 5
                 8}

 

See the Statistical Analysis section further examples of functions that produce a vector from a matrix.
