Is there some way to update the FITS library used by Matlab?

Matlab appears to be using a very old version of FITSIO (v3.27 circa 2013) that doesn't support files larger than ~2GB. This issue was fixed back in 2013 with version 3.36. Is there some way to point Matlab to a new build of CFITSIO?

I understand that you would like to support large FITS files on MATLAB. As you rightly pointed out, version 3.27 of 'cfitsio.dll' cannot handle files larger than 2 gigabytes on Windows machines. We are aware of this limitation and are actively working towards fixing it in a future release. As a workaround for this issue, I recommend using a Linux system or breaking the file into sizes smaller than 2.1 gigabytes.

Neither of those suggestions are reasonable options for us. Any other thoughts?

Any idea when Matlab will support the current FITS incarnation?

I've run into this issue as well and would also like to see it fixed.
