How can I find the median of each element between 2 rows

Hello I am a bit new to MATLAB syntax and get confused

I have a matrix of size 3x10.

I want to find the median between each element in the first row, and each element in the second row.

How can I do this? I will need to end up with 10 median values

% 3-by-10 matrix:
M = rand(3,10);
% median of each column:
median(M,1)

ans = 1×10

0.2939 0.2871 0.5671 0.8380 0.4499 0.5502 0.3408 0.9692 0.3886 0.3581

% 10-by-3 matrix:
M = rand(10,3);
% median of each row:
median(M,2)

ans = 10×1

0.8276 0.4754 0.6724 0.7976 0.4674 0.5106 0.6841 0.7998 0.5076 0.1331

Hi, sorry I will rephrase my question,

I learnt the median for example, from 1 to 10 is as:

ans = median(1:10)

My matrix (3x10) and I need to perform this operation between every corresponding element of the first row and the second row, so for example:

in position (1,1) of the matrix I have the value 100, and in position (2,1), I have 500, how can I do this operation for every corresponding element? (e.g. in this case the hard code would be median(100:500) )

Given integers a and b, with a<=b, the median of a:b (i.e., the median of all integers between a and b inclusive) is (a+b)/2, so to do that for each pair of elements in the first and second rows you could say:

M = randi(100,3,10) % 3x10 matrix of random integers between 1 and 100

M = 3×10

74 21 56 66 92 10 35 42 10 47 68 30 54 30 16 17 63 19 82 24 21 95 78 11 30 93 94 4 26 82

(M(1,:)+M(2,:))/2

ans = 1×10

71.0000 25.5000 55.0000 48.0000 54.0000 13.5000 49.0000 30.5000 46.0000 35.5000

If a>b, then what should median(a:b) give you? Maybe [] or maybe median(b:a)
