deploypcode(source_​dir, target_dir, varargin)

This entry is ideal for those who have a project they need to deploy to P-files, but they want to retain HELP contents for all of their deployed files.

DEPLOYPCODE recursively creates p-code versions of m-files in a given folder
DEPLOYPCODE(SOURCE, TARGET) will recursively search the SOURCE folder for all .m files and
deploy them as P-files to the TARGET folder using default options below.

DEPLOYPCODE(..., 'PropertyName',VALUE,'PropertyName',VALUE,...) uses the following options
when deploying p-code:

'recurse' - When true (default) will recursively deploy p-code from SOURCE folder.

'ignoreStrings' - String or cell array of strings of filenames to ignore. Regular expression
syntax is used.

'ignoreSVN' - Additional true/false option to ignore ".svn" directories. Equivalent to
adding {'^\.svn$'} to "ignoreStrings". Defaults to TRUE for convenience.

'includeHelp' - MATLAB's pcode() removes all comments including the help section from
files when run. Setting this option to true (default) will export an
additional .m file containing only the help contents of the file being
deployed. This means that myFunction.m will be deployed to myFunction.p,
but calling "help myFunction" will still return help text.

'updateOnly' - When true, destination p-files will only be created if they don't yet
exist or are older than the m-file being encoded. Defaults to false.

'copyDirectStrings' - String or cell array of strings of filenames to copy directly to TARGET
folder without encryption. Regular expression syntax is used.

'copyFigFiles' - Additional true/false option to copy ".fig" files directly. Equivalent to
adding {'\.fig$'} to "copyDirectStrings". Defaults TRUE for convenience.
'copyDllFiles' - Additional true/false option to copy ".dll" files directly. Equivalent to
adding {'\.dll$'} to "copyDirectStrings". Defaults TRUE for convenience.
'copyMexFiles' - Additional true/false option to copy mex files directly. Defaults TRUE
for convenience.

'flattenFileTree' - When true (default), regular m-files are deployed as p-files only to the
TARGET folder initially provided (rather than under any subdirectories).
When this option is set to FALSE, the file structure under the SOURCE
directory will be replicated at the TARGET.

Example:
deploypcode('C:\sven\ASSEMBLA_sahm\matlab\sahm\','U:\SAHM\matlab\_includes\sahm','updateOnly',true)

Author's note:
While I am generally against unnecessary encryption of .m files (it would be against the spirit of this file exchange, for one), I needed a tool such as this one for my work, and thought that others may need the same.
