hello all,,
please help me to solving my problems,,
i've some problem in matlab's code especially in looping
my example like this ,,
i've two examples of data
First | Second
8 | 9
7 | 8
New data : (6 6)
and then i wanna insert that data into a formula and that data would be like this
x = (First Data - New Data(1))² + (Second Data - New Data(2))²
Example :
x1 = (8 - 6)² + (9 - 6)²;
x2 = (7 - 6)² + (8 - 6)²;
but i'm so confused about looping in matlab.
I don't know how to convert that formula into matlab's code.
Can someone help me please?
this is my code
%----------I N P U T----------------------
a= input ('Input Number of Data :');
for c=1:a
int2 = ['Input The First Score - ',num2str(c),' :'];
int3 = ['Input The Second Score - ',num2str(c),' :'];
b{c,1} = input(int2);
b{c,2} = input(int3);
end;
d = cell2mat(b);
for i=1:c
for j=1:2
x(i,j)=??????????????
end
end
disp(x)
Please help me :'(

No need to use cells for b, and you should pre-allocate it as well:
b=zeros(a,2); %pre-allocate!!
for c=1:a
int2 = ['Input The First Score - ',num2str(c),' :'];
int3 = ['Input The Second Score - ',num2str(c),' :'];
b(c,1) = input(int2);
b(c,2) = input(int3);
end;
There's also no need to use a loop to compute x. You can do it in one line as follows
x = ( b(:,1) - NewData(1)).^2 + (b(:,2) - NewData(2)).^2;
