rvec

 vec=rvec(x)

 Function to convert any d input to row vector output

 A general problem arrises because man Matlab
 functions operate over only 1 dimension, but often
 one wants them to operate over all dimensions
 (eg. sum, mean, std etc.).
 Can get around this by wrapping the operand in a
 a function that makes it 1D. eg:
 
 std(rvec(x))

 Another case where this is useful is where one
 selects ranges of a multi dimensional array and
 wants the result to come out as a row or column vector
 in a single step. eg:
 
 rvec(img(:,:,3))
