normalize(A,"range") function throwing error of "Too many input arguments." in Matlab 2023a.

I am using Matlab 2023a and trying to use normalize function as given in the document

A = 1:5;
Ns = normalize(A,"scale")

It gives me the following error.

Too many input arguments.

Please run this command and show us the complete output:

which normalize -all

Remove the GEOM2D toolbox from the search path.

[Aquatris]

Essentially you are not using the matlab built-in normalize function since you have geom2d toolbox with a normalize script overwriting the builtin one.

Thanks @Stephen23 and @Aquatris. The built-in normalize was confused with geom2d's normalize. I think its better to rename geom2d normalize.

" I think its better to rename geom2d normalize."

You will have to also check and possibly rename every NORMALIZE function call within that badly-written toolbox... and probably also the names of every other function that are defined by that toolbox.

Simpler to remove the badly-written toolbox from the search path.

Move "Q:\matlab-toolbox\geom2d" with pathtool to the bottom and save. If it is in your startup file apply -end like this:

addpath Q:\matlab-toolbox\geom2d -end;

[Stephen23]

That is risky:

• GEOMED then calls the wrong NORMALIZE
• one badly-named function hints that there might be more...

Is there a way MATLAB thows a warning when more than one functions exist with the same name in the path directories?

"Is there a way MATLAB thows a warning when more than one functions exist with the same name in the path directories?"

No. Because this is completely normal and expected (e.g. overloaded functions).
