Hi Everyone,
Suppose I have the following
A = 4
and
Z = [1 9 2 3 4 5]
how do I remove the value A from Z, to get
Z = [1 9 2 3 5]
Regards,
Ulrik.

A = 4;
Z = [1 9 2 3 4 5]
Z1 = Z(find(Z~=A))
that should work

Z(Z==A) = [];
Warning: if you have floating point numbers instead of integers, you will usually need to compare with a tolerance instead of ==

You can also use setdiff function.
a=4;
z=[1 9 2 3 4 5];
setdiff(z,a)

If the function were to be put into MatLab, the answer actually comes out to be an ordered version, missig the a:
ans = 1 2 3 5 9
close, but not quite

You may pass 'stable' as additional input to setdiff, to prevent sorting:
a=4;
z=[1 9 2 3 4 5];
setdiff(z,a,'stable')

Yes, that would work, but I would recommend simply:
Z=Z(Z~=A);

HI
Im facing the same problem, but the size of A is more than one.
so Z=Z(Z~=A); does not work. Is there an alternative?
Thanks
