I’m pretty new to linear algebra so please bear with me. I’m just looking for some clarification on what a vector is. So I’ve always known a vector to be a magnitude in some direction. Basically a line with some value in some direction. I’m now learning about row and column “vectors”, except I thought these would be matrices. Just for example, I have a vector of test grades, ranging from 0-100. There’s no linearity, just a bunch of different values in a column matrix. What makes this a vector, or why is this called a column vector. There’s multiple magnitudes and no direction. I’m confused on this terminology, can somebody help clarify?
