how to write the boundary values for ode

i have the boundary values like

a(0)=1, a'(1)=0

and

b(1)=1, b'(0)=0

is this following code correct for my boundary

function [pl,ql,pr,qr] = pdex4bc(~,ul,~,ur,~)
pl = [ul(1)-1;0];
ql = [0;1];
pr = [0;ur(2)-1];
qr = [1;0];

If f = DuDx and a=u(1), b=u(2), this should be correct.
