Function Documentation

info()

function info

(

)

Return a MATLAB string and the corresponding cache file path containing the current system information.

Returns

txt : The output scalar MATLAB string containing the current system information.
cache : The output scalar MATLAB string representing the path to the cache file containing the current system information.
The returned cache file path has the form:

<DIR>/.info<YEAR><MONTH>.cache<br>

where,

1. <DIR> is replaced by the directory containing the function pm.sys.info(),
2. <YEAR> is replaced by the current year,
3. <MONTH> is replaced by the current month.

This means that the cache file contents are supposed to be updated only every month if necessary.
A cache file is generated because retrieving system information is an expensive shell command-line operation.
The time expense is particularly notable on Windows systems.

Possible calling interfaces ⛓

[txt, cache] = pm.sys.info()

Example usage ⛓

cd(fileparts(mfilename('fullpath'))); % Change working directory to source code directory.
addpath('../../../'); % Add the ParaMonte library root directory to the search path.
 
pm.matlab.show()
pm.matlab.show('pm.sys.info()')
pm.matlab.show( pm.sys.info() )
 
pm.matlab.show()
pm.matlab.show('[str, cache] = pm.sys.info();')
                [str, cache] = pm.sys.info();
pm.matlab.show('cache')
pm.matlab.show( cache )
pm.matlab.show('str')
pm.matlab.show( str )

Example output ⛓
