It means you called a function and requested an output that was never created in the workspace of the function. Here's a simple example
    function out=test(in)
     in+1; %out not created

    end
Now if I do the following, I get an error because I've asked for an output 'z', but a value for this is never created inside the function
    >> z=test(1)
    Error in test (line 3)
     in+1; %out not created
    Output argument "out" (and maybe others) not assigned during call to "C:\Users\mjacobson\Documents\mwjtree\test\test.m>test".
Notice, however, that calling the function without output arguments
 >> test(1)
gives no errors.
