Determine the version when the specified function was introduced to MATLAB.
Results are returned with the version number and a link to the webdocs page.
The specified function does not need to exist in the current installation.
Based on when() by Reza Ahmadzadeh
https://www.mathworks.com/matlabcentral/fileexchange/54483-when-when-a-function-was-introduced-by-matlab
Reworked to:
  • fix compatibility with changes to website formatting
  • allow lookup of functions not in the current installation (due to version or missing toolbox)
  • accomodate functions where the webdocs URL cannot be blindly predicted (e.g. createMask)
  • allow function name cell array to have any geometry
  • attempt detection of renamed functions
Some fallback search functionality requires R2014b or newer; otherwise, this should work for earlier versions (tested in R2009b).
