A.2. CLASS TASK 323
A.2.207
Task.putmaxnumqnz()
Task.putmaxnumqnz(maxnumqnz)
Changes the size of the preallocated storage for quadratic terms.
Arguments
maxnumqnz :
Description:
long
Number of non-zero elements preallocated in quadratic coefficient matrixes.
MOSEK stores only the non-zero elements in Q. Therefore, MOSEK cannot predict how much
storage is required to store Q. Using this function it is possible to specify the number non-zeros
to preallocate for storing Q (both objective and constraints).
It may be advantageous to reserve more non-zeros for Q than actually needed since it may
improve the internal efficiency of MOSEK, however, it is never worthwhile to specify more than
the double of the anticipated number of non-zeros in Q.
It is never mandatory to call this function, since its only function is to give a hint of the amount
of data to preallocate for efficiency reasons.
A.2.208
Task.putmaxnumvar()
Task.putmaxnumvar(maxnumvar)
Sets the number of preallocated variables in the optimization task.
Arguments
maxnumvar :
Description:
int
Number of preallocated variables in the optimization task.
Sets the number of preallocated variables in the optimization task. When this number of variables
is reached MOSEK will automatically allocate more space for variables.
It is never mandatory to call this function, since its only function is to give a hint of the amount
of data to preallocate for efficiency reasons.
Please note that maxnumvar must be larger than the current number of variables in the task.
