Insert rows from one matrix into another

I have two matrices that have the same number of columns, something similar to this. Matrix A has 57 rows and B has 9.

A = 2373 259 18.10 23.80  0.20                   
    2500 272 17.00 23.40 -0.10   
    3000 273 29.20 20.50 -1.30                   
    ...                                          
    ...

B = 2593 273 21.00 22.00 -0.70
    3400 280 26.69 24.77  0.50
    ... 
    ...

I want to test whether the value in the first column of B (2593) is between two values in the first column of A (2500 & 3000). I want to perform this test by looping though each row in B and comparing to the analogous values in A. Then I want to insert each row of matrix B between the appropriate rows in A so that the numbers in the first column are in ascending order...

A = 2373 259 18.10 23.80  0.20
    2500 272 17.00 23.40 -0.10
    2593 273 21.00 22.00 -0.70
    3000 273 29.20 20.50 -1.30
    3400 280 26.69 24.77  0.50
    ...

I tried this, but it said the index exceeds matrix dimensions. Not sure how else to proceed.

for i=1:numel(B)(1:end,1)
    for j=1:numel(A)(1:end,1)
        if (B(i,1) < A(j,1) && B(i,1) > A(j+1,1))
             vertcat(A, B(i,:), A(j,:))
        end
    end
end

use sortrows() command as follows:

A = [2373 259 18.10 23.80  0.20; ...
     2500 272 17.00 23.40 -0.10; ...
     3000 273 29.20 20.50 -1.30];

B = [2593 273 21.00 22.00 -0.70; ...
     3400 280 26.69 24.77  0.50];

% merging the two data sets as you asked.
ABmerged=sortrows([A;B],1);

ABmerged
2373.00  259.00   18.10   23.80    0.20 
2500.00  272.00   17.00   23.40   -0.10 
2593.00  273.00   21.00   22.00   -0.70 
3000.00  273.00   29.20   20.50   -1.30 
3400.00  280.00   26.69   24.77    0.50

The solution was much simpler than I was making it. Thanks so much for the help!
