Y = diff(X)
Y = diff(X, n)
Y = diff(X, n, dim)
| Parameter | Description |
|---|---|
| X | vector or matrix (real or single) |
| n | difference order: positive integer scalar or [] |
| dim | dimension: positive integer scalar |
| Parameter | Description |
|---|---|
| Y | difference array: vector or matrix. |
If X is a vector of length n, result of diff(X) is a vector of first differences X(2) - X(1), ..., X(n) - X(n-1).
If X is a matrix, result of diff(X) is a matrix of column differences along the first non-singleton dimension.
