When you use aDataGeneratorobject to generate data for aDataSpecificationobject with theDimensionsproperty set to 1, the output data always contains the minimum and maximum values of the specified intervals, and any values specified by theMandatoryValuesproperty.

When you generate data for aDataSpecificationobject with theDimensionsproperty set to a value greater than 1, the output is generated by taking a cartesian product of the one-dimensional output.

For example, consider the following twoDataSpecification对象. The two objects are identical except that one is one-dimensional, and the other is two-dimensional.

dataspec_1d = fixed.DataSpecification('single',...'Intervals', {-1,1},'Dimensions',1); dataspec_2d = fixed.DataSpecification('single',...'Intervals', {-1,1},'Dimensions',2);

datagen_1d = fixed.DataGenerator('DataSpecifications',...dataspec_1d,'NumDataPointsLimit', inf); datagen_2d = fixed.DataGenerator('DataSpecifications',...dataspec_2d,'NumDataPointsLimit', inf);

Get the size of the generated data for each of the configurations.

size_1d_data = size(outputAllData(datagen_1d)) size_2d_data = size(outputAllData(datagen_2d))

size_1d_data = 1 244

size_2d_data = 2 59536

TheDataGeneratorgenerates complex data in a similar way to the two-dimensional data. Create aDataSpecificationobject withDimensionsset to1and theComplexityset tocomplex. Create aDataGeneratorobject using this specification.

dataspec_complex = fixed.DataSpecification('single',...'Intervals', {-1,1},'Dimensions', 1,'Complexity','complex');

datagen_complex = fixed.DataGenerator('DataSpecifications',...dataspec_complex,'NumDataPointsLimit', inf);

Get the size of the generated data from this configuration.

size_complex_data = size(outputAllData(datagen_complex))

size_complex_data = 1 59536

The length of the output data for the one-dimensional complex data is the same as the length of the two-dimensional real data.
