excel - Public function using a Select Case statement spits out #VALUE! errors -

-

based off of statement in book, calculating whichever pv=nrt value choose select case letter.

public function athing(solvefor string, v1 single, v2 single, v3 single, v4 single) variant  dim p single dim v single dim n single dim r single dim t single  select case solvefor  case "p"     n = v1     r = v2     t = v3     v = v4 athing = n * r * t / v  case "v"     n = v1     r = v2     t = v3     p = v4 athing = n * r * t / p  case "n"     p = v1     v = v2     r = v3     t = v4 athing= p * v / (r * t)  case "r"     p = v1     v = v2     n = v3     t = v4 athing = p * v / (n * t)  case "t"     p = v1     v = v2     n = v3     r = v4 athing = p * v / (n * r)  case else athing = "can't find varialbe solve for, again"  end select  end function

if put number in select case's place, returns else case. if place case's letter inside, returns #value! error, meaning somehow have incorrect input somewhere.

the function located inside module, shouldn't issue.

is there obvious?

the solution, replacing letters of case "" numbers. excel dislikes having letters , numbers inside functions, dunno why. using 0-4 represent pv=nrt appear in equation. 

public function athing(solvefor string, v1 single, v2 single, v3 single, v4 single) variant  dim p single dim v single dim n single dim r single dim t single  select case solvefor  case "0"     n = v1     r = v2     t = v3     v = v4 athing = n * r * t / v  case "1"     n = v1     r = v2     t = v3     p = v4 athing = n * r * t / p  case "2"     p = v1     v = v2     r = v3     t = v4 athing= p * v / (r * t)  case "3"     p = v1     v = v2     n = v3     t = v4 athing = p * v / (n * t)  case "4"     p = v1     v = v2     n = v3     r = v4 athing = p * v / (n * r)  case else athing = "can't find variable solve for, again"  end select  end function

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a
