It is common, especially when plotting data, to generate an array of numbers with a uniform spacing.
The only time when the distinction between row and column vectors is crucial is when performing linear algebra operations, which is discussed in the final chapter. Thus cargo_weights is a 1×6 array, while Stargell_homeruns is 21×1.įor the applications covered in this chapter, the distinction between row and column vectors is unimportant, although when operations combining vectors are performed, their dimensions must be consistent. In the third case, the numbers were separated by semi-colons this creates a column vector. A row vector containing N elements has dimensions 1xN, while a column vector has dimensions Nx1. The reason is that in the first two cases, the numbers were separated by commas or spaces – this creates a row vector. Notice that the first two arrays are displayed horizontally, while the third is displayed vertically.
