Hello community,

I am trying to use a function which is in another package called model in one class. I am trying to import the package like this so I can use the function Parametros_Entrada.

However, I get an error all the time that says the following: Undefined function 'Parametros_Entrada' for input arguments of type 'double'. I tried to change the function to the project root and it works well, the problem is that the import does not take it well. I have tried ifferent things with the import but none comes out like:

import model.*
import model.Parametros_Entrada.m
import @model.*
import @model.Parametros_Entrada

And so on...Could you help me?

Thank you so much!

Gabriela

Your folder, Model, is not a Matlab package. Package folders always begin with the + character. See Packages Create Namespaces.

IMO: The Matlab function, import(), is of little use (with Matlab m-code), you need to repeat it in every function. I never use it, instead I write the fully qualified names.
