How to call a mexw64 function?

Hi.

I am trying to run a script in matlab which calls a mexw64 function. I have read previous questions regarding this issue, but I still cannot find a way to call it properly.

I have the following error:

Undefined variable "function" or class "function.mexw64"

What I have tried is the following:

The mexw64 function is in the same folder as the script where is being called.

I have matlab2018 and MS Windows (both of them 64 bits) and the MinGW64 Compiler

Please... Any suggestion to solve this problem?

Is the mex file already compiled? (i.e. do you already have the .mexw64 file)

[Walter Roberson]

If it is already compiled, then just refer to the name without the .mexw64 . For example if you had a MadHatter.mexw64 then your could would just invoke MadHatter(with appropriate arguments)

Hi. Yes, I have already my file:

andorsdk3functions.mexw64

and also i am calling it from my script as a normal function.

init = andorsdk3functions('AT_InitialiseLibrary');

Not sure if it is a typo, but you mex file name and the function name are not the same: the latter contains a 3 in the middle.

[Hugo Huerta]

Yes, it was a typo, It was missing the 3 when I wrote the comment.

They are correct in my code. Thanks.

Can you see the function from the command line:

which andorsdk3functions -all

Then type the following at the MATLAB command line:

dbstop if error

Then run your code. When the error occurs, figure out why your code cannot see your function. E.g., what does this show now:

which andorsdk3functions -all

Hi.

This is what I get:

>> which andorsdk3functions -all
'andorsdk3functions' not found.

[Walter Roberson]

First I recommend that you look in the File Exchange for File Association Fix.

After that I would suggest that in MATLAB you command

rehash

If there is still a problem after that then a dll needed by the mexw64 might be missing.

You could also check for unprintable characters in the file name. E.g.,

d = dir;
dname = {d.name};
ismember('andorsdk3functions.mexw64',dname)
