Given a finite number of vectors in a real vector space, a conical combination or a conical sum of these vectors is a vector of the form
where the real numbers satisfy
The name derives from the fact that a conical sum of vectors defines a cone (possibly in a lower dimensional subspace).

Famous quotes containing the word combination:
“By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.”
—Abraham Lincoln (1809–1865)
