dsp.ArrayVectorAdder

添加阵列以沿指定的维度向矢量

expand all in page

Description

TheArrayVectorAdder对象将N-D阵列添加到沿指定维度的向量。矢量的长度必须沿指定维度等于N-D阵列的大小。

添加一个一天沿着指定的数组来一个向量dimension:

Define and set up your array-vector addition object. SeeConstruction。
Callstep根据属性添加N-D阵列dsp.ArrayVectorAdder。The behavior ofstepis specific to each object in the toolbox.

Note

Starting in R2016b, instead of using thestep执行由System Object™定义的操作的方法，您可以使用参数调用对象，就像它是一个函数一样。例如，y = step(obj,x)和y = obj(x)perform equivalent operations.

Construction

ava = dsp.arrayveleradder.返回一个数组矢量加法对象，ava, that adds a vector to an N-D array along the first dimension.

ava = dsp.arrayvectoradder（'财产Name',财产Value, ...)返回一个数组矢量加法对象，ava, with each property set to the specified value.

Properties

方面

方面along which to add vector elements to input

Specify the dimension along which to add the input array to the elements of the vector as a positive integer. The length of the vector must match the size of the N-D array along the specified dimension. The default is1。

VectorSource

传染媒介的来源

Specify the source of the vector values as |Input port|财产|。默认为Input port。

Vector

Vector values

Specify the vector values. This property applies only when you set theVectorSourceproperty to财产。默认为[0.5 0.25]。此属性可调整。

定点属性

FullPrecisionOverride

全精确override for fixed-point arithmetic

Specify whether to use full precision rules. If you setFullPrecisionOverrideto真的, which is the default, the object computes all internal arithmetic and output data types using full precision rules. These rules provide the most accurate fixed-point numerics. It also turns off the display of other fixed-point properties because they do not apply individually. These rules guarantee that no quantization occurs within the object. Bits are added, as needed, to ensure that no roundoff or overflow occurs. If you setFullPrecisionOverridetofalse, fixed-point data types are controlled through individual fixed-point property settings. For more information, seeFull Precision for Fixed-Point System Objects。

`圆形的ingMethod`	定点操作的圆形方法指定舍入方法为\|`Ceiling`\|`Convergent`\|`地面`\|`Nearest`\|`圆形的`\|`最简单的`\|`Zero`\|。默认为`地面`。仅当对象不处于完全精度模式时，此属性才适用。
`溢出`	固定点操作的溢出动作 Specify the overflow action as \|`Wrap`\|`Saturate`\|。默认为`Wrap`。仅当对象不处于完全精度模式时，此属性才适用。
`VectorDataType`	Vector word and fraction lengths Specify the vector fixed-point data type as \|`Same word length as input`\|`风俗`\|。设置时，此属性适用`VectorSource`property to`财产`。默认为`Same word length as input`。
`customVectordataType.`	Vector word and fraction lengths Specify the vector fixed-point type as a`numerictype.`与A的对象`签名`的`汽车`。设置时，此属性适用`VectorSource`property to`财产`和the`VectorDataType`property to`风俗`。默认为`numerictype.([],16,15)`。
`AccumulatorDataType`	Accumulator word and fraction lengths Specify the accumulator fixed-point data type as \|`全精确`\|`Same as first input`\|`风俗`\|。默认为`全精确`。
`风俗AccumulatorDataType`	Accumulator word and fraction lengths Specify the accumulator fixed-point type as a scaled`numerictype.`与A的对象`签名`的`汽车`。This property applies only when the`AccumulatorDataType`属性是`风俗`。默认为`numerictype.([],32,30)`。
`OutputDataType`	Output word and fraction lengths 指定输出固定点数据类型为\|`与累加器相同`\|`Same as first input`\|`风俗`\|。
`风俗OutputDataType`	Output word and fraction lengths Specify the output fixed-point type as a scaled`numerictype.`与A的对象`签名`的`汽车`。This property applies only when theOutputDataType属性是`风俗`。默认为`numerictype.([],16,15)`。

Note：此示例仅在R2016B或更高版本中运行。如果您使用的是早期版本，请将每个呼叫替换为相同的函数stepsyntax. For example, myObject(x) becomes step(myObject,x).

Add a 2-by-1 vector to a 2-by-2 matrix along the first dimension of the array.

ava = dsp.arrayveleradder.; a = ones(2); x = [1 2]'; y = ava(a, x);
