innerArrayGrow

protected void innerArrayGrow(int N)

Description copied from class: Tensor

Re-declare inner array so that it is at least of length N

Specified by:

innerArrayGrow in class Tensor<Tensor_F64>

Parameters:

N - Desired minimum length of inner array

innerArrayLength

protected int innerArrayLength()

Description copied from class: Tensor

Length of inner array as returned by "data.length"

Specified by:

innerArrayLength in class Tensor<Tensor_F64>

Returns:

Length of inner array

create
