Re: Mex Error

[Rafal]

The MEX file did not compile properly, but it would be difficult for me to say what went wrong based on the error message. 

I assume you ran `compilePyrTools.m` and then compiled the compiled the MEX files to the `matlabPyrTools_1.4_fixed` folder. This should work. 

I would recommend that you use instead version 3.0.7, which does not require any MEX files. 

Another option is to run the 2.2.1 on Ubuntu or Windows, which should hopefully work with the precompiled MEX files. 

Best,

Rafal

Hello,

i am using hdrvdp 2.2.1 on MATLAB2023 and i am getting the follwing Error:

I did successfully compile the MEX. And I'm quite new to Matlab, so I'm not really sure what the problem is.

It would be great if someone could help me out :)
