◆ numlines()

function numlines ( in idname )

Return a scalar MATLAB integer representing the number of lines in the specified input idname.

Parameters

[in]

idname

: The input scalar MATLAB object that can be either:

a MATLAB string containing the path to a record-based external file whose number of records (lines) must be returned.
a MATLAB integer, representing the file ID of an opened record-based file whose number of records (lines) must be returned.

Returns: nlines : The output scalar MATLAB integer containing the number of records (lines) in the specified input idname.

Possible calling interfaces ⛓

: nlines = pm.io.numlines(idname);

Warning: The input file (ID) will be closed even if it is open upon entry to the function.

Example usage ⛓

: 1cd(fileparts(mfilename('fullpath'))); % Change working directory to source code directory.

2addpath('../../../'); % Add the ParaMonte library root directory to the search path.
