Error: "MATLAB cannot run this file because c:\~~~ shadows it. delete shadowing file and try again"

Hi I've a question about matlab simulink when I run a code, there are message

"MATLAB cannot run this file because c:\~~~ shadows it. delete shadowing file and try again"

what's the problem? And why this happen??

[Noah Vawter]

Hi, I found this happened when I had a .m and .slx file with the same base name. When I renamed the .m file, I could run it again.

bad: my_model.m, my_model.slx good: my_model_parameters.m, my_model.slx

[biber alex]

you are right.thanks.

[Sarvocch Gupta]

Thanks, it solved my problem!

[Giulia Panico]

I had the same problem. Thanks!

[Alexander Wallberg]

Same problem here! Thanks!

There is a pecking order of files to run when several files of the same base name are visible (i.e. in the current directory or on the path). E.g., if the current directory has a file named myfunction.m and myfunction.mexw32, MATLAB will run the latter because mex files are higher in the pecking order than m-files. You have a similar situation. You have more than one file with the same base name and because of different extensions or location one of them is shadowing (i.e. is higher in the pecking order than) the other. Examine the error message in detail to discover what the files are. You can also type this at the command line to discover all of the visible files with the same base name:

which basename -all

Thanks, eliminate error.

Rename the file name. that is, don't use the same mfile name with the slx file

[Manikandan]

Thank you for the solution.

I have renamed the files. But each time when i open simulink the links for constants are broken. So i have to go to mscript to run the code and save the parameters in workspace and then come back to simulink to run the sumulation. then it works fine.

Is this the same everytime? Appreciate your reply.

doesnt help me,the file name is not found.

[Walter Roberson]

Please post a copy of the error message, showing which file it says is doing the shadowing.

[sridevi engg.college]

it shows basename not found

[Walter Roberson]

sridevi engg.college, please post a complete copy of the error message.

basename is not the name of any routine used in MATLAB with any of the toolboxes I have. It is, however, the name of an OS-X and Linux executable that by standards convention should be at /usr/bin/basename . If you see a message about basename not being found, it is likely coming from outside MATLAB, such as a problem in starting up MATLAB itself due to the PATH environment variable being incorrect.

It is possible, though, that you could be executing MATLAB code that uses unix() or system() to try to invoke some shell commands that include basename and that is not being found, either due to PATH corruption or due to you being on MS Windows.

[Walter Roberson]

When @James Tursa posted in 2015,

which basename -all

he did not mean basename literally; he meant that you were to fill in the basic name of what you were searching for. For example,

which myfunction -all

which might potentially return back listings for myfunction.m and myfunction.mexw64

Hello ,

I faced same problem ,but what I did to resolve is ! keep file name for the code(Script) and model different.
