Function Documentation

copy() [1/2]

void copy	(	ConstIterator6D	origin,
		const ConstIterator6D &	end,
		Iterator6D	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,
		Iterator6D	target,
		const Iterator6D &	end
	)

Copy a scalar to all elements.

debug_tensor6view_get_elem()

Numeric debug_tensor6view_get_elem	(	Tensor6View &	tv,
		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

tv	TensorView
v	Vitrine index
s	Shelf index
b	Book index
p	Page index
r	Row index
c	Column index

operator<<()

ostream& operator<<	(	ostream &	os,
		const ConstTensor6View &	v
	)

Output operator.

This demonstrates how iterators can be used to traverse the tensor. We use the standard output operator for Tensor5 to print each page in turn.

transform()

void transform	(	Tensor6View	y,
		double(&)(double)	my_func,
		ConstTensor6View	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

y	Output: The results of the function acting on each element of x.
my_func	A function (e.g., sqrt).
x	A tensor.
