CORE_cpltmg_condexq generates the Q used in condex matrix generation
See http://www.mathworks.fr/fr/help/matlab/ref/gallery.html#f84-999898 gallery('condex',n,4,100)
Returns a "counter-example" matrix to a condition estimator. It has order n and scalar parameter theta (default 100).
LAPACK (RCOND): It is the inverse of this matrix that is a counter-example.
[in] | M | The number of rows of the matrix Q used in condex generation. M >= 0. |
[in] | N | The number of columns of the matrix A to be generated. N >= 0. |
[out] | Q | On entry, the M-by-3 matrix to be initialized. On exit, the housholder reflectors required for condex generation. |
[in] | LDQ | The leading dimension of the matrix Q. LDQ >= max(1,M). |
