I don't absolutely have to use the Euclidean distance, but it does need to be something that takes into consideration the values GSD. You will have to index into it anyway.Sorry, I misunderstand. This function fully supports tall arrays. Calculates the L1 norm, the Euclidean (L2) norm and the Maximum(L infinity) norm of a vector. On the other hand, MATLAB uses "length" to denote the number of elements nin a vector. Why do you say that the log10 is a mathematical error? Would it be faster to create a new dummy variable Cdum=C(:,2:9);?No that does not matter. Why do you say that the log10 is a mathematical error?

Note that norm(x)is the Euclidean length of a vector x. I want to find a parameter value that makes a row in C that minimise the difference between C and G, which takes into account the effect of the standard deviations.
which is probably a tad faster, I do, however, prefer the The floating point should handle the large magnitude of the input data, up to a certain point with With 1e7 values in the +/- 1e5 range, you may expect the square of the Euclidian distance to be in the +/- 1e17 range (5+5+7), which both formats will handle with ease.In any case, you should vectorize the code to remove the loop (which Matlab has a history of handling very inefficiently, especially in older versions)I however believe that the use of log10 is a mathematical error. GSD actually at standard deviations of each point in G. Each row of C are predictions of G.I'm just looking at these again.

I'd like to calculate the Euclidean distance between a vector G and each row of an array C, while dividing each row by a value in a vector GSD.
