How can I run publish() in a workspace other than base?

I'm using the publish() function to build up an automated reporting process. BUT, whenever I call publish() from within a function, it attempts to execute its target in the MATLAB base workspace, not the workspace of the present function. The following code generates an error:

function callingFunction()
a = 10;
publish(myReportingScript)

where myReportingScript.m contains:

disp(a)

If there is no variable a in MATLAB's base workspace, this simply doesn't work. Surely publish() should be executing in the workspace of its caller, not always the base workspace??? How can I get around this?

[Note: I also tried converting my script to a function and calling with:

function callingFunction()
a = 10;
options.codeToEvaluate = 'myReportingFcn(a)'
publish(myReportingFcn)

... but that doesn't work either.

Not a full answer, but I developed a workaround which adds the requisite variables to the base workspace then deletes them after publishing.

Requires:

- putvar(), on the FEX, from John d'Ericco (John saves me yet again!)

- care that this doesn't overwrite then delete similarly named variables in that workspace.

    options.codeToEvaluate = 'myReportingFcn(a)';
    putvar(a)
    publish('trainFoilReport.m',options)
    evalin('base','clearvars a')
