Error in debug mode: Method not defined or removed from search path.

I recently updated from R2013a to R2016a and now my way of experimenting in debug-mode causes an error, which I cannot remember I ever seen before (my memory might be short). The error is: "Method ... not defined ... or removed from ... search path."

Example from a session:

• Execution is halted by a break-point (and possibly stepped) into a public method of the class, h5pia.StringTree.
• I want to try a call to the public method, find_wildcard, of the same class. methods(this) confirms that the method exists
• I made an interactive call, ix_b01 = this.find_wildcard('B01'), which caused the error. See below.
• I clicked Continue and got the error again. And clicked Quit
• Back at the &gt&gt prompt calls to several of my functions returned "... not found". &nbsp plot(1:12) worked.
• The GUI, Set Path, indicated that the path was okay.
• Finally, rehash path solved the problem - temporarily(?).

K>> methods(this)
Methods for class h5pia.StringTree:
StringTree            find_root2node        is_child              strcmp                
add_node              find_wildcard         is_leaf               strcmp_wildcard       
...

K>> ix_b01 = this.find_wildcard( 'B01' )
Error using h5pia.StringTree/find_wildcard
Method 'find_wildcard' is not defined for class 'h5pia.StringTree' or is removed from 
MATLAB's search path.

here I gave up and hit continue

Error using TestResult/addError
Method 'addError' is not defined for class 'TestResult' or is removed from MATLAB's search
path.

Error while evaluating UIControl Callback

Ouestions:

• Has anyone else encountered this issue?
• Is there a way to avoid this error when experimenting in debug-mode?

Hi per,

If rehash path resolves the issue at least fro the current session, you can save the path by executing the following command in MATLAB Command Window:

>> rehash path

>>savepath

For more details, refer to the following link:
