Generating scalars from Approximate values

Hi, I would like Matlab to generate two scalars whose values are equal to the corresponding values of the first and last column of the matrix when columns 2:5 are approximate to another 1x4 vector.
That's to say.. whenever columns two through five are (as closely as possible) approximate to the 1x4vector, then I want the two scalars to be generated.

can you please show a small, simple example to explain what you want? thanks

If the columns 2 through 5 are not closely enough approximate to the 1x4 vector, then what should be the output result for that row?

Is your matrix actually a row vector? I hope so, or you will have to clarify how an n-by-4 array is to approximate a 1-by-4 vector.
Even if your array is a row vector, what kind of approximations is it that you need? Is three matching values, no matter how large the difference between the fourth values, a good match? Is it the magnitudes that must be within a tolerance? You need to be more specific...
if (matching condition)
sc1 = arr(1);
sc2 = arr(6);
end
