diff
diff(arr)
diff(arr, dim)
Create a new matrix or array with the difference of the passed matrix or array.
Dim parameter is optional and used to indicant the dimension of the array/matrix to apply the difference
If no dimension parameter is passed it is assumed as dimension 0
Dimension is zero-based in javascript and one-based in the parser
Arrays must be 'rectangular' meaning arrays like [1, 2]
If something is passed as a matrix it will be returned as a matrix but other than that all matrices are converted to arrays
Try it yourself:
| $1 | A = [1, 2, 4, 7, 0]
| |
| $2 | diff(A)
| |
| $3 | diff(A, 1)
| |
| $4 | B = [[1, 2], [3, 4]]
| |
| $5 | diff(B)
| |
| $6 | diff(B, 1)
| |
| $7 | diff(B, 2)
| |
| $8 | diff(B, bignumber(2))
| |
| $9 | diff([[1, 2], matrix([3, 4])], 2)
