There was no change to cellfun. You are (were?) misusing eval inside of an anonymous function, In R2015b and later MATLAB will not let you get away with it. Copied directly from the help page:
- Use only explicit variables when constructing anonymous functions. If an anonymous function accesses any variable or nested function that is not explicitly referenced in the argument list or body, MATLAB throws an error when you invoke the function. Implicit variables and function calls are often encountered in the functions such as eval, evalin, assignin, and load. Avoid using these functions in the body of anonymous functions.
There are tricks that will allow it to be seen in the eval but you are much better off re-coding this in a way that does not use eval.
