WebDec 29, 2024 · Unit Normal Vector. Just as knowing the direction tangent to a path is important, knowing a direction orthogonal to a path is important. When dealing with real-valued functions, we defined the normal line at a point to the be the line through the point that was perpendicular to the tangent line at that point. WebOne of the basic vector operations is addition. In general, whenever we add two vectors, we add their corresponding components: (a, b, c) + (A, B, C) = (a + A, b + B, c + C) (a,b,c) + (A,B,C) = (a + A,b + B,c + C) This works in any number of dimensions, not just three. WebThe result is a column vector of the elements in A that are less than 9. Since B is a logical matrix, this operation is called logical indexing. In this case, the logical array being used as an index is the same size as the other array, but this is not a requirement. ...
