Purpose Alter the input size by padding or truncating rows and/or columns.
Library Signal Operations
Description The Pad block changes the size of the input matrix from M
i
-by-N
i
to M
o
-by-N
o
by padding or truncating along the rows, the columns, or both dimensions. The
dimensions of the output, M
o
and N
o
, are specified by the Number of output
rows
and Number of output columns parameters, respectively. The value
with which to pad the input is set by the
Value parameter.
The behavior of the Pad block and Zero Pad block are identical, with the
exception that the Pad block can pad the input matrix with values other than
zero. See the Zero Pad block reference for more information on the behavior of
the Pad block.
