Hi @Ach,
For finding the minimum values for each row in a matrix, you can use the "min" function in MATLAB.
You can use the min function for your requirement as follows:
rng default % for reproducibility
A = rand(5,10)
A = 5x10
0.8147 0.0975 0.1576 0.1419 0.6557 0.7577 0.7060 0.8235 0.4387 0.4898 0.9058 0.2785 0.9706 0.4218 0.0357 0.7431 0.0318 0.6948 0.3816 0.4456 0.1270 0.5469 0.9572 0.9157 0.8491 0.3922 0.2769 0.3171 0.7655 0.6463 0.9134 0.9575 0.4854 0.7922 0.9340 0.6555 0.0462 0.9502 0.7952 0.7094 0.6324 0.9649 0.8003 0.9595 0.6787 0.1712 0.0971 0.0344 0.1869 0.7547

% use min function to get smallest element from each row.
[min_numbers,idx] = min(A,[],2) % idx refers to the postition of the minimum number in the row
min_numbers = 5x1
0.0975 0.0318 0.1270 0.0462 0.0344

idx = 5x1
2 7 1 7 8
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
% use mean function
result = mean(min_numbers)
result = 0.0674
You can refer to the following example in the 'min' function documentation
I hope this helps resolve the query.
