A. Write a function for selecting and reading a pdb file.

i (The function does not receive input.

ii (Output: Structure with fields corresponding to pdb format.

iii (The function works as follows:

(1 (Asking the user to select a file (uigetfile command with output of file name and folder name).

(2 (composes the full name of the file (including path space on disk) and reads it the output argument of the function.

the function is like this:

function kovetz= A()
[choseK,choseD]=uigetfile('*.ent','shemkovetz');
kovetz=pdbread([choseK,choseD,]);
end

but i have an error that says
