— Function File: postpad (x, l, c)
— Function File: postpad (x, l, c, dim)

Prepends (appends) the scalar value c to the vector x until it is of length l. If the third argument is not supplied, a value of 0 is used.

If length (x) > l, elements from the beginning (end) of x are removed until a vector of length l is obtained.

If x is a matrix, elements are prepended or removed from each row.

If the optional dim argument is given, then operate along this dimension.
