How can I get the column number of a matrix with smallest error to my value?

Hey,

The code below finds values("Tempvalue") 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?

Output x should be the column number of RGB where the value with the smallest error occurs.

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 % x should be the column number of RGB with smallest error to Tempvalue

end

Mybe you can use:

[x,y,z]=find(....)
