It appears that the code uses the indicated variable inside a parfor loop, but evidently the code does not initialize the variable before the loop. This message can indicate:

• A coding problem, because the code should initialize the variable.

• Code Analyzer’s inability to determine when the code sets the variables. In this case, Code Analyzer could produce an incorrect message.

  For example, Code Analyzer could be unaware of variables set by the load function.

If the code uses the variable, initialize it (for correctness and efficiency). If the message is incorrect, suppress it as described in Adjust Code Analyzer Message Indicators and Messages.
