		std::vector< float > &	res
	)

Multiplies the matrix mat with the vector vec and saves the result in the vector res.

Parameters:

mat	The matrix, which should be multiplied.
vec	The vector, which should be multiplied.
res	The vector the result should be saved in.

void printMat

mat

)

Prints the given matrix to the standard-output.

Parameters:

mat	The matrix, which should be printed.

void printVec

(

std::vector< float > &

vec

)

Prints the given vector to the standard-output.

Parameters:

vec	The vector, which should be printed.

float strToFloat

(

std::string &

str

)

Converts a string to float.

Parameters:

str	The string, which should be converted.

Returns:

The converted float.

void vecAdd	(	std::vector< float > &	vec1,
		std::vector< float > &	vec2,
		std::vector< float > &	res
	)

Adds the vectores vec1 and vec2 and saves the result in the vector res.

Parameters:

vec1	The first vector, which should be added.
