Function Documentation

◆ copy() [1/2]

void copy ( ConstIterator7D  origin,
const ConstIterator7D end,
Iterator7D  target 
)

Copy data between begin and end to target.

Target must be a valid area of memory. Note that the strides in the iterators can be different, so that we can copy data between different kinds of subtensors.

◆ copy() [2/2]

void copy ( Numeric  x,
Iterator7D  target,
const Iterator7D end 
)

Copy a scalar to all elements.

◆ debug_tensor7view_get_elem()

Numeric debug_tensor7view_get_elem ( Tensor7View tv,
Index  l,
Index  v,
Index  s,
Index  b,
Index  p,
Index  r,
Index  c 
)

Helper function to access tensor elements.

Because of function inlining the operator() is not accessible from the debuggger. This function helps to access Tensor elements from within the debugger.

Parameters
tvTensorView
lLibrary index
vVitrine index
sShelf index
bBook index
pPage index
rRow index
cColumn index

Numeric max ( const ConstTensor7View x)

Max function, tensor version.

◆ operator<<()

std::ostream & operator<< ( std::ostream &  os,
const ConstTensor7View v 
)

Output operator.

This demonstrates how iterators can be used to traverse the tensor. We use the standard output operator for Tensor6 to print each page in turn.

◆ transform()

void transform ( Tensor7View  y,
double(&)(double)  my_func,
ConstTensor7View  x 
)

A generic transform function for tensors, which can be used to implement mathematical functions operating on all elements.

Because we have this, we don't need explicit functions like sqrt for tensors! The type of the mathematical function is double (&my_func)(double). Numeric would not work here, since mathematical functions for float do not exist!

transform(y,sin,x) computes y = sin(x)

The two views may be the same one, in which case the conversion happens in place.

Parameters
yOutput: The results of the function acting on each element of x.
my_funcA function (e.g., sqrt).
xA tensor.
