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 ...
You can use theisempty,size, andlengthfunctions to identify empty object arrays. For example, create an empty array of theColorInRGBclass defined in the previous section. A = ColorInRGB.empty(0,5); isempty(A) ans = logical 1 size(A) ...
arrayfundoes not support heterogeneous arrays whenUniformOutputis set totrue. Difference in Behavior for Input Arrays of Complex Numbers If the input arrayAis an array of complex numbers, and some of the elements have imaginary parts equal to zero, then callingarrayfunand indexing into the array ...
public staticObjectnewInstance(Class<?> componentType, int length) throwsNegativeArraySizeException Creates a new array with the specified component type and length. Invoking this method is equivalent to creating an array as follows: int[] x = {length}; Array.newInstance(componentType, x); ...
TheArrayclass is not part of theSystem.Collectionsnamespaces. However, it is still considered a collection because it is based on theIListinterface. TheArrayclass is the base class for language implementations that support arrays. However, only the system and compilers can derive explicitly from the...

-or- length is less than zero. ArgumentException items is not null, and the lower bound of keys does not match the lower bound of items. -or- items is not null, and the length of keys is greater than the length of items. -or- index and length do not specify a valid range in ...
For example, Void is not supported. -or- elementType is an open generic type. ArgumentOutOfRangeException length is less than zero. Examples The following code example shows how to create and initialize a one-dimensional Array. C# Copy Run using System; public class SamplesArray { public ...
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...
