Dear Sir, please provide the solution to the following error. In this program, i am select the three images at a time and display the all images through the function. For this i wrote a program in this way

clc
clear all
close all
n=inputdlg('enter the number of images');
n=str2num(n{:});
for i=1:n
    [file,path]=uigetfile('*.*','select one image');
    g{i}=imread([path,file]);
    g{i}=rgb2gray(g{i});

end
for i=1:n
display_ima(g{i})
end

%program 'display_ima(g{i})'
function display_ima(g{i})
figure,imshow(g{i})

But i have following errors
Error: File: display_ima.m Line: 1 Column: 23
Unbalanced or unexpected parenthesis or bracket.
