I'm from Brazil and I'm involved with programming language teaching for, at least, ten years. I have a background in computer science and my colleagues tend to use the term
vector to describe an array in programming languages like C or Java. I particularly HATE this use of the therm vector, since vectors and matrices are mathematical entities that can be added, multiplied and so on, while arrays and multidimensional arrays can't. I know that there are languages that these constructs exists, like MATLAB, but they don't exists natively in the most used general purpose programming languages. In Java there is an data structure called
Vector, that is, in fact, a synchronized list that can't be added, for exaxmple. C++ also has a
vector data structure/container in STL that is a list too and is not a mathematical vector.
I always explain this for my students, that some people call arrays as vectors and multidimensional arrays as matrices and that this is kinda wrong. I tell them that an array can be used to represent a vector, but that it is not a vector! The same for matrices.
I would like to know what do you think about it! Do you think that is correct or not to call arrays as vectors? If so, why? Is this "missconception" common in your country?
I'm sorry if I sounded pedantic. My confusion was introduced by one of my professors during my undergraduate course. He was a mathematician/physicist working with computer science. Maybe this was the reason. I will correct it now, thank you!
