◆ copy() [1/4]

void copy	(	ConstIterator1D	origin,
		const ConstIterator1D &	end,
		Iterator1D	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 for example copy data between different kinds of subvectors.

◆ copy() [3/4]

void copy	(	ConstIterator2D	origin,
		const ConstIterator2D &	end,
		Iterator2D	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 for example copy data between different kinds of subvectors.

Origin, end, and target are 2D iterators, marking rows in a matrix. For each row the 1D iterator is obtained and used to copy the elements.

cross3

Calculates the cross product between two vectors of length 3.

c = a x b, for 3D vectors. The vector c must have length 3 and can not be the same variable as a or b.

◆ debug_matrixview_get_elem()

Numeric debug_matrixview_get_elem	(	MatrixView &	mv,

Helper function to access matrix elements.

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

◆ mult() [1/2]

void mult	(	VectorView	y,
		const ConstMatrixView &	M,
		const ConstVectorView &	x
	)

Matrix Vector multiplication.

y = M*x. Note that the order is different from MTL, output comes first! Dimensions of y, M, and x must match. No memory reallocation takes place, only the data is copied. Using this function on overlapping MatrixViews belonging to the same Matrix will lead to unpredictable results. In particular, this means that A and B must not be the same matrix! The implementation here is different from the other multiplication routines. It does not use iterators but a more drastic approach to gain maximum performance.

◆ operator<<() [2/2]

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

Output operator.

This demonstrates how iterators can be used to traverse the matrix. The iterators know which part of the matrix is `active', and also the strides in both directions. This function is a bit more complicated than necessary to illustrate the concept, because the formating should look nice. This means that the first row, and the first element in each row, have to be treated individually.

◆ proj()

void proj	(	Vector &	c,

Calculates the projection of two vectors of equal length.

c = proj_a(b). Projecting b on a. The vector c must have the same length but can not be the same variable as a or b.

c	Out: The projection of b on a.
a	In: A vector of length N.
b	In: A vector of length N.

◆ transform() [1/2]

void transform	(	VectorView	y,
		double(&)(double)	my_func,
		ConstVectorView	x
	)

A generic transform function for vectors, 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 matrices! 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)

Although the matrix version of this can also be used for vectors, thanks to the automatic interpretation of a vector as a one column matrix, this one is slightly more efficient. However, the difference is very small (only a few percent).

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 vector.

◆ transform() [2/2]

void transform	(	MatrixView	y,
		double(&)(double)	my_func,
		ConstMatrixView	x
	)

A generic transform function for matrices, 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 matrices! 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)

This function can also be used for Vectors, because there is a conversion to MatrixView.

The two Matrix 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 matrix.
