Upper Triangular Matrix

Famous quotes containing the words upper and/or matrix:

    “All men live in suffering
    I know as few can know,
    Whether they take the upper road
    Or stay content on the low....”
    William Butler Yeats (1865–1939)

    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)
