Upper Triangular Matrix

Famous quotes containing the words upper and/or matrix:

    You doubt we read the stars on high,
    Nathless we read your fortunes true;
    The stars may hide in the upper sky,
    But without glass we fathom you.
    Ralph Waldo Emerson (1803–1882)

    As all historians know, the past is a great darkness, and filled with echoes. Voices may reach us from it; but what they say to us is imbued with the obscurity of the matrix out of which they come; and try as we may, we cannot always decipher them precisely in the clearer light of our day.
    Margaret Atwood (b. 1939)
