i need to find a minimum row value in a matrix. eg
A=[12 64 76; 34 10 27; 9 8 20; 10 30 8]
And the desired output would be min value of row = [9 8 20] which is row number 3.
is there any function can do this? I noticed that min () function is used to find the minimum value in a row NOT minimum row value.

This might be a little late, but the min(min()) function would do the trick

Do you mean to say, you want the row with the minimum maximum value?
A=[12 64 76; 34 10 27; 9 8 20; 10 30 8];
[value,ind] = min(max(A,[],2));
A(ind,:)
ans =
9 8 20
Or
A = [ 7 9 5; 3 8 7; 4 5 6]
[value,ind] = min(max(A,[],2));
A(ind,:)
ans =
4 5 6

You have not told us what aspect of rows you are minimizing. I will guess you want the row index of the row with the least sum.
[c,ix] = min(sum(A,2));
The value 'c' is the minimum row sum and 'ix' is that row's index.

If you want row that contains the minimum value (it is not clear to me what "minimum row" means):
[x xi] = min(A(:));
xij = ind2sub(xi,size(A));
minrow = A(xij(1),:);

Can you please define what "minimum row" means? What is the minimum row of the following matrix (and why)?
[ 7 9 5;
3 8 7;
4 5 6]
