In the figure, the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using ...
The transpose (indicated by T) of any row vector is a column vector, and the transpose of any column vector is a row vector: […] = [] and [] = […]. The set of all row vectors with n entries in a given field (such as the real numbers ) forms an n -dimensional vector space ; similarly, the set of all column vectors with m entries forms an m ...
More generally, there are d! possible orders for a given array, one for each permutation of dimensions (with row-major and column-order just 2 special cases), although the lists of stride values are not necessarily permutations of each other, e.g., in the 2-by-3 example above, the strides are (3,1) for row-major and (1,2) for column-major.
rank(A) = number of pivots in any echelon form of A, rank(A) = the maximum number of linearly independent rows or columns of A. [5] If the matrix represents a linear transformation, the column space of the matrix equals the image of this linear transformation. The column space of a matrix A is the set of all linear combinations of the columns in A.
These elementary row operations include the multiplication of a row by a nonzero scalar and the addition of a scalar multiple of a row to one of the rows above it. For example: [ 1 3 − 1 0 1 7 ] → add row 2 to row 1 [ 1 4 6 0 1 7 ] . {\displaystyle {\begin{bmatrix}1&3&-1\\0&1&7\\\end{bmatrix}}{\xrightarrow {\text{add row 2 to row 1 ...

The blue numbers list the number of edits displayed on a page—20, 50, 100, 250 or 500. A higher number increases the length of a page, but reduces the number of pages. The number you select replaces n in the links to the previous or next pages, e.g., (newer 100 / older 100).
One fairly easy way to make these elevations available in articles would be to use a bot to add them to Wikidata, for all Wikidata entities that have coordinates. Perhaps better would be to do it on Wikidata through an extension that caches the data, so that it doesn't require actual bot edits for the system to work, but doesn't require looking ...
