Function Documentation

◆ copy() [1/2]

void copy	(	ConstIterator5D	origin,
		const ConstIterator5D &	end,
		Iterator5D	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,
		Iterator5D	target,
		const Iterator5D &	end
	)

Copy a scalar to all elements.

◆ debug_tensor5view_get_elem()

Numeric debug_tensor5view_get_elem	(	Tensor5View &	tv,
		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
s	Shelf index
b	Book index
p	Page index
r	Row index
c	Column index

◆ max()

Max function, tensor version.

◆ min()

Numeric min ( const ConstTensor5View & x )

Min function, tensor version.

◆ operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		const ConstTensor5View &	v
	)

Output operator.

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

◆ swap()

void swap	(	Tensor5 &	t1,
		Tensor5 &	t2
	)

Swaps two objects.

◆ transform()

void transform	(	Tensor5View	y,
		double(&)(double)	my_func,
		ConstTensor5View	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.
