COLVEC (matrix) ;

This function is supported by the IML procedure and the iml action.

The COLVEC function is part of the IMLMLIB library. The COLVEC function converts a matrix into a column vector. If matrix is any matrix, the COLVEC function returns an vector that contains the elements of matrix in row-major order. The first m elements in the vector correspond to the first row of the input matrix, the next m elements correspond to the second row, and so on, as shown in the following example.

x = {1 2 3,
     4 5 6};
y = colvec(x);
print y;

See the ROWVEC function for converting a matrix into a row vector.
