Join elements of an array
显示 更早的评论
If I have two array
a=[1 2 3 0]
b=[0 0 5 4]
and I want the array c=[1 2 3 4] How should I proceed?
In other words I want a array c in which the element of array a==0 is replaced with the element of matrix b.

What happened to the 5? Why did you leave that out of c?

a=[1 2 3 0]
b=[0 0 5 4]
idx=a==0
bb=sort(nonzeros(b))
a(idx)=bb(1:sum(idx))
