I use the function as follows:
the length of arrays a and b are 3569442 and 1156736,respectively.
when I choose nzmax=9452356, I find that my sample code cannot run due to this error: program Exception - access violation.
at case of nzmax=1500000 ,the program could run ,but the result is not correct
I want to know whether it appears Memory overflow due to the value of the nzmax .
