public TensorSupport(Environment<V> environment)

Method Detail

calculate

public final <C> OngoingTensorOperation<C,V> calculate(Tensor<V> tensoric)

Allows to perform calculation on given tensoric.

Parameters:

tensoric - to calculate with.

Returns:

expression to calculate.

zeros

public Tensor<V> zeros(Shape shape)

returns a ZERO value Tensor for given Shape.

Parameters:

shape - to use.

Returns:

a Tensor of given Shape filled with 0.0;

ones

public Tensor<V> ones(Shape shape)

returns a IDENTITY value Tensor for given Shape.

Parameters:

shape - to use.

Returns:

a Tensor of given Shape filled with field identities;

elementInverseOf

public Tensor<V> elementInverseOf(Tensor<V> tensor)

Parameters:

tensor - to use.s

Returns:

a Tensor with field inverse values

negativeOf

public Tensor<V> negativeOf(Tensor<V> tensor)

Parameters:

tensor - to use

Returns:

a Tensor of negative values

resample

public OngoingFieldAwareResamplingStart<V> resample(Tensor<V> tensor)

Starting clause for a fluent expression to resample a tensor, using structural resamplings (e.g. repeating), but also field aware resamplings (e.g. linear interpolation). For example:

 
 Tensoric<Double> resampled = resample(aDoubleTensor)
                           .repeat(String.class)
                           .then().linear(Integer.class, Integer::doubleValue)
                           .toTensoric();
 
 

Note: The order of the options is important, as the resampling will be performed in the given order!

For options which do not require a field, see the version in TensorStructurals.resample(Tensor).

Parameters:

tensor - the tensor to be resampled

Returns:

an object to define further the strategy for resampling.
