function b = targetSort(a,t)
[m,n]=sort(abs(a-t),'descend');
k=a(n);
for i=1:length(a)
if k(i)>=t
b(i)=m(i)+t;
else if k(i)

I find [b,I]=sort(A) is really a useful method!

sortrowsc? Strange I can run this function in R2012b, but I cannot find it in help.

Óscar on 27 Sep 2012

It is a MEX file function called by sortrows. Check it out in the sortrows source code.
