Undefined function or variable

I had several runtime errors, and I closed out of MatLab to end them. Each time I returned, MatLab no longer recognized any of my functions. Now Matlab doesnt recognize any of the functions I create. I cannot create a new script and copy the function and save a new file.

I thought running this code might resolve the issues but all of my functions seized after:

restoredefaultpath 
rehash toolboxcache

thank you

Did you add the folder holding these functions to your path (and saved it)?
