Dear all,

I have a function that needs to treat data coming from a structure, and I want to have several inputs indicating which branch of the structure is the one to be treated:

function total = totalCampus(campus,building,year,var)

total=getfield(campus,(year),(building),(var))

end

This is just the first line of the function, where I want to call the specific column of the table in the structure, using dynamic fieldnames, but I can't manage. Any clue?

best regards,

Mario

在 MATLAB Online 中打开

total = campus.( building ).( year ).( var );

should work fine, assuming campus is your struct and that is a branch of the struct.

Is it defined?

"once I type tot=totalCampus(1,a2017,total,PotenciaActivaTotal_kW); it tells me that the function or variable a2017 is undefined "

You are typing those inputs without single quotes, which tells MATLAB that they are variable/function/class/etc. names. You need to use single quotes to define character vectors.
