However, if you have a locally downloaded copy of the Fortran or C Library Documentation (NAG Toolbox for MATLAB® documentation is not affected) then you will need to change the file:
and change line 4 to refer to a new location for MathJax.
The existing line is:
var nagmathjax= ((window.location.protocol=="https:") ? "https" : "http" ) + "://cdn.mathjax.org/mathjax/latest/";
The URL recommended by the MathJax consortium for users who wish to use a freely available web hosted library is:
var nagmathjax= ((window.location.protocol=="https:") ? "https" : "http" ) + "://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/";
As this change has already been applied to the copies on our website you may alternatively just download this and copy it into your local documentation.
We apologise for this inconvenience, but the underlying changes to the MathJax server arrangements are not in our control.
