How do I plot specific values from a matrix

I have 6 column 5000 row matrix: A
I would like to plot Column 1 against column 5.
e.g.
plot(A(:,1),A(:,5))
However I only want to do this when values from column 4 = 3.7 and the values from column 3 = 1.2
What is the easiest way to do this?

idx = A(:,4)==3.7 & A(:,2)==1.2;
plot(A(idx,1),A(idx,5))
Beware floating point issues!
