how to simplier this programme

Please help me to make this programme more simple. I have done this programme but my prof want it to be more simple. I tried to make it simple but it goes wrong. I think this is simple to me but not my prof… if you can help me, please do.. thanks.. this is the question.. To determine the highest, lowest and the average value of two vectors depending on user own choice by mean of MATLAB Programming.. and below this, the command that I’ve make..

disp('Welcome to my program.');
disp(' ');
disp('instruction:');
disp(' a ) Enter the number of column of a vector.');
disp(' b ) Next, enter the element for vector A and vector B.');
disp(' c ) Then, select your option of what do you want to find.');
disp(' ');
column = input (' Enter the number of column of a vector: ');
disp(' ')
disp(' Enter the element for vector A ');
for count=1:column 
    disp(['A (',num2str(count), ')=']);
    A(count)=input(' ');
end
disp(' ')
disp(' Enter the element for vector B');
for count=1:column
    disp(['B(',num2str(count),')=']);
    B(count)=input(' ');
end
disp(' ')
disp(['Vector A is [',num2str(A),')']);
disp(['Vector B is [',num2str(B),')']);
disp(' ')
disp('What do you want to find?');
disp(' ')
disp('1-find the highest value');
disp('2-find the lowest value');
disp('3-find the average value');
choose=input('Choose:');
disp(' ')

while choose >3
    disp('Sorry, please enter the right input!');
    choose=input('choose:');
end

disp('Your result:')
disp(' ')
fprintf('number of column:%2.0f\n',column);

if choose ==1
    disp('choice: find the highest value');
