IsArray函数返回一个Boolean值,表明传递给该函数的变量是否为数组。其语法为: IsArray(varname) 其中: 参数varname为等检验是否为数组的变量的名称。 如果传递给IsArray函数的变量是一个数组或者包含一个数组,则返回值为True;否则为Fa...
The Vector class lets you access and manipulate a vector — an array whose elements all have the same data type. The data type of a Vector's elements is known as the Vector's base type. The base type can be any class, including built in classes and custom classes. The base type is ...

你可以采用“工厂模式”来做，首先声明一个接口A，然后让你的Class分别继承这个接口A，你的Class里有一个标识这个类的字段，如 A是接口，B、C、D是继承接口的类。B、C、D有一个公共的唯一标识此类的字段E。代码如下：pulic A fonction_name(A parameter){ A a = null; swicht(parameter.E){ ...

The number of nonzero elements of a sparse array. The size in any given dimension. For example,zeros(0,3e9,"gpuArray")is not allowed. Distributing agpuArrayamong workers in a parallel pool using thedistributedorcodistributedfunctions is not supported. If you have multiple GPUs and each worker...
CArray is a collection class that can store the array of values with a uniform data type of one of fixed-width integer (8,16,32,64bits), floating-point number (32,64bits), complex number (64,128bits), fixed-length string, ruby object. These values are stored in memory block as bina...
Manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on (1) and false indicates the bit is off (0). C# Copy public sealed class BitArray : ICloneable, System.Collections.ICollection Inheritance Object BitArray Implements ICollection...
A = zeros(2,1); A(1) = 1; A(2) = 0 + 1i A = 1.0000 + 0.0000i 0.0000 + 1.0000i Then create a cell array and assign the elements ofAto it. When you index intoA(1), its value is returned as a real number because its imaginary part is equal to zero. And you can store...
Although this class is nonfinal, it was not designed for inheritance and should not be subclassed. In particular, self-use by overridable methods is not specified. See Effective Java Item 17, "Design and Document or inheritance or else prohibit it" for further information....
