MATLAB: Not enought input arguments

filepathinput argumentsMATLAB and Simulink Student Suite

I have this function

function comas_a_puntos (filepath)
    datos=readtable(filepath);

and in the command window I write

comas_a_puntos ("/Users/cristinaserrrano/Documents/TFM/Ensayos ruido/18173_L2_corregirarchivosruido.xlsx")

but after that in the command window appears an error

Not enough input arguments.
Error in comas_a_puntos (line 2)
    datos=readtable(filepath);

I don't know where or what the error is

comas_a_puntos ("/Users/cristinaserrrano...")
              ^ get rid of this space character!

Why the space makes a difference:

And in the function definition too:

function comas_a_puntos (filepath)
                       ^ get rid of this!

Standard practice in MATLAB does not have space characters between function names and the parentheses.

Usas

>> save('net.mat', 'net')

en lugar de

>> save('net')

El argumento segundo es el variable que quieres guardar especificamente.

Veas el documento - SAVE:

Your external function does not know which variables you use in your app. You need to pass them along. Try changing

else
  process_function(app.filepath);
end

and

function a = process_function(filepath) 
[~,filename,fileext]=fileparts(filepath);
end
