ROWVEC Function

ROWVEC (matrix) ;

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

The ROWVEC function is part of the IMLMLIB library. The ROWVEC function returns a 1 times n m vector. The specified matrix is converted into a row vector in row-major order. The returned vector has 1 row and n m columns. 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, on, as shown in the following example.

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