2015-02-15 22:22:21 +0100 | asked a question | built in method norm of Vector_symbolic_dense object So, I want to write a program that plots equipotential contours for z=0 for electric potential of 3 charges(ch) at specified coordinates(matrix m). I need rv to be a vector with general coordinates so I can later plot the equipotential contours. However, after the last line I get this: How do I fix this to get the norm of rv-m[i]? , |
