How can I find midpoint in a structure of rows?

Hello everyone,

I am trying to find every midpoint value between the min and max points that is in a row within a sturcture of rows.

Lumbar.Lift.AllMin = min(lumbar_lift,[],2);

Lumbar.Lift.AllMax = max(lumbar_lift,[],2);

This has worked with me so far. However, when I use the code below, it gives me weird values that are definetely not between the these values:

Lumbar.Lift.Allmid = min(abs(lumbar_lift-((Lumbar.Lift.AllMax + Lumbar.Lift.AllMin))/2),[],2);

your help is appirciated

a = randn(3, 10);
[nrows, ncols] = size(a);
[amin, imin] = min(a, [], 2)

amin = 3×1

-1.4505 -1.8692 -2.4076

imin = 3×1

9 2 7

[amax, imax] = max(a, [], 2)

amax = 3×1

1.8287 1.0523 0.6824

imax = 3×1

8 5 10

amed = median(a, 2)

amed = 3×1

0.5678 -0.3628 -0.6928

% mid points
for i=1:nrows
    [~, imid] = min(abs(a(i, :)-(amin(i) + amax(i))/2));        % Get the index that coloset to the "mid point"
    amid(i, 1) = a(i, imid);
end
amid

amid = 3×1

0.1543 -0.6789 -0.7695

Thank you, this has worked with me. but it gave me the values in rows and I wanted them in coumns. I tried using the transpose function, A.', A' , but non of these have worked with me. Any sugesstion? Thank you
