Runtime Error with OpenCV Core.Multiply method (Java)

edit

Hello,

Some advice here would be appreciated, been looking at this for a number of weeks.

Error given on Matrix Multiply OpenCV: Core.Multiply() Function Goal: After running SolvePnP doing simple Matrix Multiply with the following matrix dimensions : [3x3]*[3x1] = [3x1]
