14 Working with vectors and matrices
This chapter covers
- Working with numbers in matrices and performing calculations
- Slicing and dicing arrays
- Concatenating arrays along different dimensions to form larger arrays
In chapter 4, you explored basic operations, such as push!, on one-dimensional arrays, called vectors. In this chapter, you will focus more on working with multidimensional arrays, such as matrices.
What can you use a matrix and vector for? They can be combined to solve a great number of problems. For example, it is popular to use vectors in a geometric interpretation; in this case they represent points in space. You can use matrices to move and rotate these points.
Matrices can even be used to solve mathematical equations, and they ...
