padarray
B = padarray(A, padsize; padval=nothing)
Pad matrix A with an amount of padding in each dimension specified by padsize.
Args
A
: GMTimage, GMTgrid or Matrix to pad.
padsize
: Amount of padding in each dimension. It can be a scalar or a array of length equal to 2 (only matrices are supported).
Kwargs
padval
: If not specified,A
is padded with a replication of the first/last row and column, otherwisepadval
specifies a constant value to use for padded elements.padval
can take the value -Inf or Inf, in which case the smallest or largest representable value of the type ofA
is used, respectively.
Return
Padded array of same type as input.
Example
A = [1 2; 3 4];
B = padarray(A,1)
