I have an array
A = [1 2 3 -3 -2 -1 0 0 0]
of
size 1x9
I am trying to add zero at first index of this array. The result should be
Result = [0 1 2 3 -3 -2 -1 0 0 0]
Making the size of array
1x10
I have tried
A(1,:)=[];
Also
Idx=[1];
c=false(1,length(A)+length(Idx));
c(Idx)=true;
result=nan(size(c));
result(~c)=A;
result(c)=0
They both does now work for me.
Can someone guide me on this.

Thank you. After your answer, I figure out why i was having problem. My array was vertical not horizental. I have transposed it and it worked. Thanks.
