Why this error of a function that is not found in the current directory?

I get this error line "'DicomReader' is not found in the current folder or on the MATLAB path, but exists in:

C:\Users\f028368h\Downloads
C:\Echo Images\Stelios\Test
C:\Echo Images\Stelios
C:\Users\f028368h\AppData\Local\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\TempState\Downloads

Change the MATLAB current folder or add its folder to the MATLAB path.
Error in fresh>Load_image_Callback (line 142)"

DicomReader function exist in the current directory. I don't understand why MATLAB cannot find it. Any idea?

What shows up for

ls DicomReader.*
!dir DicomReader.*

[Stelios Fanourakis]

It gives the current directory where DicomReader exists

The same directory I work and at the same directory I get the above error

[Guillaume]

Does the code in the callback change the current directory? That is, is there any cd in function Load_image_Callback?

Note that there's never any need to change the current directory in matlab. Using full paths is a lot safer and prevent this kind of error.

Show us, don't just tell us -- clearly it isn't on path or in cwd.

Actually execute and show output of

cd
which DicomReader
dir DicomReader*.*
path

Thank you guys. I found a solution to this problem

@Stelios: If you share the solution with the forum, other readers can profit from this also. This is the nature of this forum.

@Jan, I really do not remember what I did and worked. I suppose it was a syntax error or order error, maybe misspelling. If I find I'll post it.

I encountered the very same problem and it was a syntax error. In my case I used:

obj = Class_Constructor( A , B , :)

This led to the error "[...] is not found in the current folder or on the MATLAB path, but exists in: ...", although it was there!

Solving the syntax problem helped:

obj = Class_Constructor( A , B , 1:4)
