6.7.13 MapToMatrix

6.7.13.1 Outline of the node

Convert the Map<int, ObjectRef> type to the Matrix<ObjectRef> > type when the ObjectRef of the given Map<int, ObjectRef> is either the Matrix<float> type or the Matrix<complex<float> > type.

6.7.13.3 Usage

When to use

This node is used to convert the Map<int, ObjectRef> type to Matrix<ObjectRef> > type when the ObjectRef of the given Map<int, ObjectRef> is either the Matrix<float> type or the Matrix<complex<float> > type. Taking a Map< int , Matrix<float> > as the input will output a Matrix<float> . Taking a Map< int , Matrix<complex<float> > > as the input will output a Matrix<complex<float> > .

6.7.13.4 Input-output and property of the node

Input

INPUT

: Map< int , Matrix<float> > or Map< int , Matrix<complex<float> > > of the Map<int, ObjectRef> type.

Output

OUTPUT

: any  type. Note that the supported data types are the Matrix<float> type and the Matrix<complex<float> > type.

Description

METHOD

string 

min_key

 

The method to convert the Map<int, ObjectRef> type to the Matrix<ObjectRef> type. Select min_key, max_key, average, or summation.

DEBUG

bool 

false

 

Enable or disable to output the conversion status to standard output.

METHOD

: string  type. The method to convert the Map<int, ObjectRef> type to the Matrix<ObjectRef> type. Select min_key, max_key, average, or summation. Selecting min_key or max_key outputs a Matrix<float> or a Matrix<complex<float> > whose key is the minimum or the maximum among the input Map<int, ObjectRef> . Selecting average or summation outputs a Matrix<float> or a Matrix<complex<float> > whose values are the summation of or the average of the values of the input Map<int, ObjectRef> . The default value is min_key.

DEBUG

: bool  type. Setting the value to true outputs the conversion status to the standard output. The default value is false.
