I am attempting to use the parfeval function. I routinely get "not enough input arguments" error. Below is a very simplified script, and this gets the same error message. This function simply is trying to open two xml files at the defined path and the filename. If I run the function directly (line commented out with "% %" the function works fine. When attempt to use with parfeval, get the "not enough input arguments" at the link "systemStruc = readstruct(..."

Eventually this will be built into a compiled version. This is very simplied sample of function code, but even this gives me the error.

%test parfeval

systemXmlPath = 'D:\myTestSystem';

systemStatusFile = 'myTestSystemStatus.xml';

WatchID = parfeval( backgroundPool, twoParameterFunction, 1, systemXmlPath, systemStatusFile );

% % result = twoParameterFunction(systemXmlPath, systemStatusFile);

disp('passed off');

function [result] = twoParameterFunction(systemXmlPath, systemStatusFile)

%default

result = false;

%set system level paths and read system defined parameters from the XML

systemStruct = readstruct(fullfile( systemXmlPath,'myTestConfiguration.xml'));
