Description: 一般性的奇异值分解算法，float浮点型。-SGGSVD computes the generalized singular value decomposition (GSVD)
* of an M-by-N real matrix A and P-by-N real matrix B:
*
* U*A*Q = D1*( 0 R ), V*B*Q = D2*( 0 R )
*
* where U, V and Q are orthogonal matrices, and Z is the transpose
* of Z. Let K+L = the effective numerical rank of the matrix (A ,B ) ,
* then R is a K+L-by-K+L nonsingular upper triangular matrix, D1 and
* D2 are M-by-(K+L) and P-by-(K+L) "diagonal" matrices and of the

Description: 独立成份分析（ＩＣＡ）以及ｗｉｎｎｅｒ滤波 Source separation of complex signals with JADE.
Jade performs `Source Separation in the following sense:
X is an n x T data matrix assumed modelled as X = A S + N where
o A is an unknown n x m matrix with full rank.
o S is a m x T data matrix (source signals) with the properties
a) for each t, the components of S(:,t) are statistically
independent
b) for each p, the S(p,:) is the realization of a zero-mean
`source signal .
c) At most one of these processes has a vanishing 4th-order
cumulant.
o N is a n x T matrix. It is a realization of a spatially white
Gaussian noise, i.e. Cov(X) = sigma*eye(n) with unknown variance
sigma. This is probably better than no modeling at a- Source separation of complex signals with JADE.

Description: 择使用数组储存数据。*x,*y分别装入观察站的地理坐标，temp装入的是温度信息，*tpx,*tpy分别用作对x,y进行快速排序（tpx[2]=8表示排在第2位的是x[8],rank[8]=2表示x[8]排在第2位）升序，rankx[i]即为最终x[i]的排名。
为了方便计算一个范围内的温度值，定义了一个long long 型的数组sum。算出比点p小的点(不包括点p本身)的所有温度值之和sum，之后范围的四点sum相加减,再对少数点做处理即可得到范围内的温度之和。sum[i][j]表示的是rankx=i,ranky=j左下方的温度之和，相当于一个hashtable（映射关系）-Optional use arrays to store data.* X,* y respectively, into the geographical coordinates of the Observatory, temp temperature information is loaded,* tpx,* tpy respectively used for x, y quick sort (tpx [2] = 8 means that in the first two rows of the is x [8], rank [8] = 2 means that x [8] ranked No. 2) ascending, rankx [i] shall be final and x [i] in the rankings. In order to facilitate the calculation of the temperature within a range that defines a long long type array sum. Point p is smaller than the calculated points (not including the point p itself) of all temperature values and the sum, sum the four points of the range after the addition and subtraction, then do not handle a small number of points can be obtained and a temperature within the range. sum [i] [j] represents the rankx = i, ranky = j the temperature of the lower left, the equivalent of a hashtable (mappings)

Description: PR值收敛的证明再次不做过多赘述，但是需要注意的是，PR值收敛的一个必要条件是矩阵A需要满足每一列的元素和都为1。如果开始时P向量中各部分值之和为一，那么在精度能够保证的情况下，每次迭代之后P向量中各部分的值之和依然是一，而每次迭代可以看成是对P向量中各部分值重新分配的过程。矩阵A中第i列的数据可以看成是第i个节点引用其他节点的概率，这些数据决定了第i个节点的PR值如何分配给其他所有节点。(a realization of page rank algorithm)
