Method Detail

equals

public boolean equals(java.lang.Object a)

Compares two tensors for equality.

Overrides:

equals in class java.lang.Object

Parameters:

a - a 3rd rank tensor

getComponent

public double getComponent(int i,
                  int j,
                  int k)

Returns a component of this tensor.

Parameters:

i - 1st index

j - 2nd index

k - 3rd index

Throws:

DimensionException - If attempting to access an invalid component.

setComponent

public void setComponent(int i,
                int j,
                int k,
                double x)

Sets the value of a component of this tensor.

Parameters:

i - 1st index

j - 2nd index

k - 3rd index

x - value

Throws:

DimensionException - If attempting to access an invalid component.

add

public Rank3Tensor add(Rank3Tensor t)

Returns the addition of this tensor and another.

Parameters:

t - a 3rd rank tensor

subtract

Returns the subtraction of this tensor by another.

Parameters:

t - a 3rd rank tensor

tensorProduct

public Rank4Tensor tensorProduct(Rank1Tensor t)

Returns the tensor product of this tensor and another.

Parameters:

t - a 1st rank tensor
