Something you are doing is attempting to "poof" a variable into existance -- that is, attempting to execute a command such as eval() or evalin() or load() with no outputs, which creates a variable without an explicit assignment statement having appeared for the variable. Or, you are trying to run a script from within a function and the script tries to assign values. In some kinds of functions (the better kind), that is an error. The best solution is not to poof at all. In the case of scripts being run from functions, rewrite the scripts as functions that return the values back, or at the very least assign every variable a value before running the script.
