Diagonal of a vector
WebJul 9, 2024 · An answer to a sort of reverse question might also help: Creating matrix A with a vector as diagonal can be done with A = Diagonal(rand(3)). Specifically, rand(3,3) as used in question creates 9 random numbers instead of only the 3 needed. – WebMar 23, 2024 · Let θ be the angle between P and Q and R be the resultant vector. Then, according to the parallelogram law of vector addition, diagonal OB represents the resultant of vectors P and Q. ∴ R = P + Q. Next, we extend DA to C and draw BC perpendicular to OC. So from O C B, we get. O B 2 = O C 2 + B C 2 ⇒ O B 2 = ( O A + A C) 2 + B C 2 ….
