How can I merge multiple column vectors into a single matrix in a programming language? I have several arrays representing different data sets, and I want to combine them into a structured format where each array becomes a column in the resulting matrix. What methods or functions should I use to achieve this?

I’ve been working on a project where I have several column vectors, and I really need to combine them into a single matrix. They’ve all got different data sets, and I think merging them could make my analysis way easier. ...Read more
