MATLAB: In a struct, how can you extract values for a vector of fieldnames

Question

Hello,

I have a struct called MyStruct. I can extract the field names with the command

MyFieldNames = fieldnames(MyStruct);

If I'm interested in extracting the values for first n of MyFieldNames, is there a way I can do this using the "getfield" command? If I try

Temp = getfield(StateSpace, MyFieldNames(1:n))

or

Temp = Temp = getfield(StateSpace, MyFieldNames)

I get an error saying, "Index exceeds matrix dimensions."

Thank you, Kevin

Answer 1

MyFieldNames = fieldnames(MyStruct);

for i=1:3

MyValues(i,1) = getfield(MyStruct,MyFieldNames{i});

end
