Lists, Vectors, Sequences
Hey,
For discussion; I have a few questions about lists, vectors, sequences, etc. In my experience, a vector indicates a direction and a value (mechanical / electrical). Vectors can be presented with Cartesian, Spherical or Cylindrical. Two or three dimensional. In the Matrix Editer you can select Vect. You can then enter as many values as you want. This is presented as a column. This vector is presented horizontally in the command line. (My HP Prime is set to textbook) Question 1: You would think that a vector can consist of only 2 or 3 values? Only if it were geometric? With multiple values, what exactly is the difference between a vector and a list? Question 2: Is a vector in the HP Prime (because you can enter many more values) a row vector or a column vector? Or does that not matter? Returning to my previous Thread “Geometry App, Distance, Intersections”. (Thanks kevin3g) Question 3: How can I see if a variable (or an object?) is a list or a sequence? How are these presented in CAS? Ps. Take my questions for granted, I have been a retired (software) engineer / consultant for offshore pipelay barges and crane vessels (tensioners, winches and ballast control and simulation systems) for a reasonable time. I’am getting old !! (I hope). I did my maths study in the sixties! I mainly use my HP Prime for my engineering hobbies. I have written several useful programs for this. This means that the HP Prime is very useful (easy to use) for engineers !! — Dirk Hartland
