getNumDataPointsInfo
Get information about number of data points in generated data
Description
returns information about the data points generated by the datainfo
= getNumDataPointsInfo(datagenerator
)fixed.DataGenerator
object, datagenerator
.
Examples
The getNumDataPointsInfo
function returns
information related to the number of data points in the data generated from a
fixed.DataGenerator
object.
dataspec = fixed.DataSpecification('fixdt(1,16,13)',... 'Intervals', {-1,1})
dataspec = fixed.DataSpecification with properties: DataTypeStr: 'sfix16_En13' Intervals: [-1,1] MandatoryValues: <empty> Complexity: 'real' Dimensions: 1
datagen = fixed.DataGenerator('DataSpecifications', dataspec,... 'NumDataPointsLimit', 20); getNumDataPointsInfo(datagen)
ans = struct with fields: Current: 20 Next: 21 Min: 5 Max: 75
The output indicates that there are currently 20 data combinations in the generated
data. The maximum number of combinations that the DataGenerator
object would produce is 75.
When the dimension of the generated data is greater than one, it can be useful to find the next possible size of generated data.
Create a DataGenerator
object where the associated
DataSpecification
object specifies 2-dimensional data.
dataspec = fixed.DataSpecification('single', 'Dimensions', 2); datagen = fixed.DataGenerator('DataSpecifications', dataspec)
datagen = fixed.DataGenerator with properties: DataSpecifications: {[1×1 fixed.DataSpecification]} NumDataPointsLimit: 100000
The DataGenerator
object uses the default limit of 100000 data
points in the generated data.
Get information about the number of data points generated.
getNumDataPointsInfo(datagen)
ans = struct with fields: Current: 99856 Next: 100489 Min: 81 Max: 130321
The current size of the generated data is 99856 points. By setting the
NumDataPointsLimit
property of the DataGenerator
object to the value specified in Max
, you can get the maximum
possible number of data combinations.
Set the NumDataPointsLimit
property of the
DataGenerator
object to the maximum possible number of data
points.
datagen.NumDataPointsLimit = 130321; getNumDataPointsInfo(datagen)
ans = struct with fields: Current: 130321 Next: 130321 Min: 81 Max: 130321
Input Arguments
Object from which you want to get information, specified as a fixed.DataGenerator
object.
Output Arguments
Information about the number of data points in the data generated from a
fixed.DataGenerator
object, returned as a structure with the
following fields.
Field | Description |
---|---|
Current | The number of data combinations in the generated data. |
Next | Next possible size of data combinations. |
Min | Minimum number of combinations of data required to be in the generated data. This number is equal to the number of boundary
values and mandatory values in the |
Max | Maximum number of combinations that could be in the generated data. |
