If the operation specified by trystring executes properly, eval simply returns. If trystring generates an error, the function evaluates catchstring. Use catchstring to specify a function that determines the error generated by trystring and takes appropriate action. The trystring/catchstring form of eval is especially useful in conjunction with the lasterr function. lasterr returns a string containing the last error message generated by MATLAB. Use lasterr inside the catchstring function to "catch" the error generated by trystring.
