I have an institutional license for Matlab and just downloaded version 2019a along with the PDE toolbox version 3.2 in order to access evaluateGradient.m. Although evaluateGradient is listed in the help page for this toolbox, the function apparently is missing from my download. I get this error:
'Undefined function 'evaluateGradient' for input arguments of type 'double'
And when I navigate to the PDE toolbox folder, the directory appears to exclude most of the functions listed in the documentation.
