MATLAB: Do I receive the error “MATLAB:un​assignedOu​tputs” when executing the stand-alone application that was generated with MATLAB Compiler 4.0 (R14)

Question

I have a function implemented as follows:

function out = test
plot(1:10);

When I call this function from MATLAB, the plot displays and the figure remains open as expected.

I then compile my function as follows:

mcc -m test

When I execute the resulting executable test.exe, I receive the following output:

 One or more output arguments not assigned during call to '$dir\test_mcr\test\test.m (test)'. 
 MATLAB:unassignedOutputs

The plot opens but then immediately closes.

This enhancement has been incorporated in Release 2006b (R2006b). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB Compiler 4.0 (R14) in the way that an error is generated when executing a stand-alone application that does not assign a value to one of its output arguments. As a workaround, remove the function's output variable:

function test
plot(1:10);

or assign a value to the function's output variable:

function out = test
plot(1:10);
out = 1;
