Hello friends.
I have a matrix A where I know the row number and the magnitude, but I don't know the column where this magnitude is
A = [ 6 5 3 1 9
2 4 6 8 5
12 14 6 18 16]
The data I have is magnitude (6) and row number (2).
What should I do to have the code tell me that in column 3 there is number 6 in row 2?
Regards

A = [ 6 5 3 1 9
2 4 6 8 5
12 14 6 18 16]
row = 2;
val = 6;
find(A(row,:)==val)
