why do I get the error ''Attempt to execute SCRIPT edge as a function:''?

I want to edge a gray scale image and I receive this error: ''Attempt to execute SCRIPT edge as a function:'' can any one help me?

Answer 1

[Walter Roberson]

Use

which edge

and that will tell you the location of the edge.m file that you created; you will need to delete or rename that edge.m to avoid interfering with using MATLAB's edge() routine.

Answer 2

Execution of script edge as a function is not supported:

E:\matlab program\edge.m

Error in edge (line 4)

BW1 = edge(I,'Canny');

[Walter Roberson]

You named your script edge.m but you are trying to call the edge() function inside the script. Within your edge.m script, edge gets resolved to the edge.m that you are executing. But your edge.m script cannot be called as a function, so you get an error.

You need to rename E:\matlab program\edge.m to something else that does not conflict with built-in MATLAB functions.
