How to run a function for each rows and columns?

11 views (last 30 days)
I have a function called distance, where the values of x0 and y0 are taken from data,
data = 150*(4*rand(2,100)-1); data = data.*rand(2,100);
where, x0 is the value of first row & y0 is the value of second row, now my concern, how to run the function to each values of x0 and y0 in data and store them in list_d
below are the A, B, C parameters,
A=0.0022;B=0.0061;c=0.4229;
Thanks in advance
function list_d = distance(x0,y0,A,B,C)
P=[x0; y0 ];
Q =-C+P(2);
n1 = 2*A^2;
n2= 3*A*B;
n3=(B^2-2*A*Q+1);
n4=-B*Q-P(1);
N = [n1 n2 n3 n4];
xT=roots(N);
list_d=[]; %list of distance
d_min = Inf;
for i =1:size(xT,1)
if isreal(xT(i)) %Test each xT
T=[xT(i); A.*xT(i)^2+B.*xT(i)+C];
d =norm(P-T);
list_d = [list_d d];
if (d < d_min)
d_min=d;
end
end
end

Well, there's no cell in sight so why use it?
Again, what's the problem in just putting your function in a loop and pass the necessary vectors to it?
