Hi Sani,

You can directly call the function with its name, provided it is in the path. For example your downloaded function name is myfun.m, then directly call with its name and required inputs in the script you want to access.

It says Undefined variable when I do that

[Sriram Tadavarty]

Is that ensured the file is in the matlab path? Does the function have any inputs and outputs? Can you show what the error is?

[sani]

I downloaded the function from here: https://www.mathworks.com/help/matlab/ref/scatter.html

the error messege is:

scatter_kde.m

Undefined variable "scatter_kde" or class "scatter_kde.m".

Hi Sani, i didn't see any function with name scatter_kde.m, in that page.

[sani]

sorry wrong URL, this it the one: https://www.mathworks.com/matlabcentral/fileexchange/65728-scatter-plot-colored-by-kernel-density-estimate

Thanks for the link. May i know if the example provided in the function, works? Like, try help scatter_kde in command promt and run the example.

[sani]

yes it works

Then, it should work if used in script directly. Use it with scatter_kde(x,y) in the script
