WebFeb 8, 2024 · A plane is defined by the vector normal to the plane, and by ONE point in the plane. These vectors are normal to the plane. I found them by subtracting off one of the points (the first one) from all of the other rows.

WebA simple call to arrayfun and unique will suffice: out = arrayfun (@ (x) A (b == x), unique (b), 'uni', 0); What this will do is for each unique value in b, we extract out the corresponding locations in A that match and put them into a cell array. Given your small example: b= [1 2 2 3 4 1 2 1 4]; .... and A is simply: A = 1:numel (b); WebTo define vector division as the scalar result of one vector "divided" by another, where the scalar times the denominator vector would then give us the numerator vector, we can write the following: u → = w v → u → ⋅ v → = w v → ⋅ v → ∴ w = u → ⋅ v → v 2 The math for a scalar quotient works. That is one way to divide out a vector Share Cite
