Ughh right when im half way threw writing this the computer shut off :(anyways here hope this helps.An item in a matrix is called an entry or an element. The example has entries 1, 9, 13, 20, 55, and 4. Entries are often denoted by a variable with two subscripts, as shown on the right. Matrices of the same size can be added and subtracted entry wise and matrices of compatible sizes can be multiplied. These operations have many of the properties of ordinary arithmetic, except that matrix multiplication is not commutative, that is, AB and BA are not equal in general. Matrices consisting of only one column or row define the components of vectors, while higher-dimensional (e.g., three-dimensional) arrays of numbers define the components of a generalization of a vector called a tensor. Matrices with entries in other fields or rings are also studied. Matrices are a key tool in linear algebra. One use of matrices is to represent linear transformations, which are higher-dimensional analogs of linear functions of the form f(x) = cx, where c is a constant; matrix multiplication corresponds to composition of linear transformations. Matrices can also keep track of the coefficients in a system of linear equations. For a square matrix, the determinant and inverse matrix (when it exists) govern the behavior of solutions to the corresponding system of linear equations, and eigenvalues and convectors provide insight into the geometry of the associated linear transformation. Matrices find many applications. Physics makes use of matrices in various domains, for example in geometrical optics and matrix mechanics; the latter led to studying in more detail matrices with an infinite number of rows and columns. Graph theory uses matrices to keep track of distances between pairs of vertices's in a graph. Computer graphics uses matrices to project 3-dimensional space onto a 2-dimensional screen. Matrix calculus generalizes classical analytical notions such as derivatives of functions or exponential to matrices. The latter is a recurring need in solving ordinary differential equations. Surrealism and Dictaphones are musical movements of the 20th century that use a square mathematical matrix to determine the pattern of music intervals. A major branch of numerical analysis is devoted to the development of efficient algorithms for matrix computations, a subject that is centuries old but still an active area of research. Matrix decomposition methods simplify computations, both theoretically and practically. For sparse matrices, specifically tailored algorithms can provide speedups; such matrices arise in the finite element method, for example

The values are stunning, however the equations are not working.

The film or the matrix in the film. The film is just a bit of entertainment the matrx in the film was the robots way of keeping control of people and keeping them alive to use them as energy for themselves(like a battery. This is explained in the first film by Morpheous before neo is unplugged) At the very end of the third film Smith had taken over the matrix. when Neo killed him all the Smiths died and the Matrix was re-set back to a proper world again Neo had to kill him, if he killed him the machines would leave Zion alone. The machines needed Smith dead, he was rebelling. First he took over the matrix what would it be next? hope that helps

Sequestration is a word applied to a cut in government spending. In this recent case, the cut turned out only to be a reduction in the amount of an increase, so the net result of the supposed cut was still an increase. This all brings up how the government fudges numbers to make more spending look like a reduction, and how the official story is a gross deception intended to mislead the American people. The fiscal cliff is another deception, being less a cliff than a tiny bump given the total amount of government spending. You could write an interesting paper on how the government misleads people with false statements and deception in its efforts to spend massive amounts of money it does not have.
