I am a beginner of MKL. In my research, I need to count the number of elements in a large vector
that satisfy somecriterion. For example, counting the number of elements whose absolute
values are less than 50. I checked all functions and didn't find the one that can do this job.
I would appreciate if you have any good suggestion. Thanks in advance.

MKL doesn't contains similar routines. That function is pretty simple and you can try to develop it by yourself.
Or I 'drecommend to tryippsCountInRange function from another Intel Performance Library - IPP. That function
computes the number of elements of the vector whose values are in the specified range.

Thank you for your suggestion. I tested ippsCountInRange function. Except that this function only supports integer input and I have to convert the data type before calling it, it works well and it is fast. Thanks,
