二、数组array:多维的同一类型集合(字符型、数值型、逻辑型、复数型),R可以很容易地生成和处理数组,特别是矩阵matrix是一个二维数组。 1.可以通过定义dim(维度)将向量变成matrix。 AI检测代码解析 a=c(1,3,4,5,6,7,8,9,3) > dim(a)=c(3,3) > a [,1] [,2] [,3] [1,] 1 5 8 [2,] 3...

1、c+中vector的用法(The use of vector in c+)C+s built-in array supports the mechanism of containers, but it does not support the semantics of container abstractions. To solve this problem, we implement such a class ourselves. In standard C+, container vectors (vector) are used. The ...
This is in stark contrast to a raster representation consisting of an array of color values. Raster images quickly show artifacts under scale or perspective mappings. Our goal in this chapter is to present a method for accelerating the rendering of vector representations on the GPU....

The Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created. ...
