How do I extract non zero minimum value and its index from a specific row??

for ex, C=[0,10,8,9,7;10,0,10,5,6;8,10,0,8,9;9,5,8,0,6;7,6,9,6,0]; i need min value from row 1 greater than zero. How do i get it?

If you want the minimum value greater than 1 from all the rows, then simply replace the values below 1 by inf and take the minimum:

C = [0,10,8,9,7;10,0,10,5,6;8,10,0,8,9;9,5,8,0,6;7,6,9,6,0];
tempC = C;
tempC(C < 1) = inf;
[minofrow, whichcolumn] = min(tempC, [], 2)

I mean extracting non zero row minimum from any randow row

Have you tried the code? It gives you the minimum greater (or equal( than one for each row. You can then use basic indexing to get the row that interest you.

Note that if you want the non-zero minimum instead of minimum greater than 1, then use

tempC(C == 0) = inf;

instead.
