How can I find a Value with the smallest error in my Matrix?

Hey,

The code below finds values("Tempvalues") out of a predefined RGB Scale ("RGB"), output "x" shall be the number of the row this value occurs.

How can I find the value of a Matrix "Tempvalue=100x3" within a "RGB=875x3" Matrix with the smallest error if an exact value doesn´t exist in this matrix?

Thanks for you help, if any questions feel free to ask :)

Greetings Lukas

x=0;

for i=1:100

Tempvalue=RGBTemp(i,:);

x=find(ismember(RGB,Tempvalue,'rows'));%will give you the column numbers of RGB that match Tempvalue

if x~=0

break;

end

else % How can i find the value of "Tempvalue" in "RGB" with the smallest error

end

min(abs(RGB-Tempvalue));
