matrix_mult()

Numeric matrix_mult	(	Index	k,
		Index	m,
		Index	n,
		Index	ntests,
		Index	nsubtests,
		bool	verbose
	)

Perform matrix multiplication test.

Creates to random m times k matrix A and a random k times n matrix B and computes C = A * B, C = A^T * B, C = A * B^T, C = A^T * B^T unsing the mult function from matpackI.cc. The result is verified using the mult_general functions. In addition to the operations above, ntests numbers of random submatrices of A and B are generated and their multiplication is also tested. Returns the maximum element-wise, relative error that occurred in the tests.

Parameters

[in]	k	Dimension over which the multiplication is performed.
[in]	m	Number of rows of A.
[in]	n	Number of coluns of B.
[in]	ntests	Number of standard multiplications to be performed.
[in]	nsubtests	Number of submatrix multiplications to be performed.
[in]	bool	If verbose is true the results of each test are printed to standard out.

Returns

The maximum element-wise, relative error that occured in the tests.

nlinspace()

void nlinspace	(	Vector &	x,
		const Numeric	start,
		const Numeric	stop,
		const Index	n
	)

nlinspace

Linearly spaced vector with specified length.

Returns a vector equally and linearly spaced between start and stop of length n. (equals the Matlab function linspace)

The length must be > 1.

Parameters

x	Output: linearly spaced vector
start	first value in x
stop	last value of x <= stop
n	length of x
