zero padding

how zero padding is done in matlab with matlab code

[Hans Scharler]

I saw your Discussion thread @Image Analyst and thought maybe there is a MATLAB answer for this question - https://www.mathworks.com/matlabcentral/discussions/tips/845271-trick-to-enlarge-a-matrix-by-padding-it-with-zeros

Answer 1

Refer to padarray function.

[Sean de Wolski]

Image Processing Toolbox required.

[DGM]

While it wasn't an option in 2011, MIMT does have a wrapper function padarrayFB(), which will work either with or without IPT installed. Downloading MIMT just for a simple zero padding task seems a bit like overkill, but I guess it depends what it's worth.

If you're using release R2023b or later, see the paddata function introduced in MATLAB in release R2023b.
