a non-sharing smart pointer class that can be used with STL containers such as std::map, VECTOR, list, set, and deque. The smart pointer has an assignment operator and greater than operator that call the target object s operator.
This is SvmFu, a package for training and testing support VECTOR
machines (SVMs). It s written in C++. It uses templates. The
advantage of templates is that the types of kernel values and data
points can be varied to suit the problem.
LINEINTRGAL Line Integral in a 2D VECTOR Field.
LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C.
X and Y define the coordinates of a rectangular grid over which
U and V are defined. X and Y must be monotonic and 2D plaid as
％ produced by MESHGRID. X, Y, U, and V must all be the same size.
按照官方的說法：Cairo is a VECTOR graphics library with cross-device output support.
翻譯過來，就是cairo是一個支持多種輸出的向量圖形庫。
具體解釋一下，也就是說，cairo是種畫圖的工具庫，他可以向多種設備上畫圖，比如：
cairo可以輸出到png,可以輸出到pdf，可以輸出到ps，可以輸出到xlib，可以輸出到XCB，可以輸出到win32，以后還要輸出到svg
我們可以展望一下，如果cairo能夠統一linux下所有的畫圖接口，那么，所見所得可能就會成為顯示。
