Hi all. I am having some difficulties to associate the values in a matrix.I have a simple matrix C=[ 1 2; 3 4;6 7] and two variables: x=3 and y. My objective is to see all values in the first column and when the number 3 is achieved variable y must be equal to 4.I have created a simple routine but i am not being able to "finish it". Any suggestions would be very helpful:
x=3;
for m=1:size(C,1)
for n=1:size(C,1)
if C(:,1)==x
y=%here are my problems i think
end
end
end

regards

C=[ 1 2; 3 4;6 7];
x=3;
y=C(C(:,1)==x,2);
