padarray {matlab} | R Documentation |
Pad array.
padarray(A, padsize, padval = 0, direction = c("both", "pre", "post"))
A |
vector, matrix, or array to be padded | ||||||
padsize |
integer vector specifying both amount of padding and the dimension along which to add it | ||||||
padval |
scalar value specifying pad value, which defaults to 0. Instead, it may specify the method used to determine pad values. Valid values for the method are:
| ||||||
direction |
character string specifying direction to apply padding. Valid values are:
|
This is an S4 generic function.
Return value is the same type as argument A
with requested padding.
