I have an array. I want to add zero at its beginning. e.g my array has 761 elements. 'd' is array which has 761x1 dimension in this case. i want to make 762 elements by adding first element as zero. gFx has dimension of 762x1 so i created a new array of zeros having size of gFx. then i apply a for loop.it worked, but it exceeds matrix dimensions. i also used break statement but it didn't work.so if someone knows whats wrong ,feel free to help!
[a,b]=size(gFx);
new_d=zeros(a,b);
for i=1:length(gFx)
if (d(i)~=0)
new_d(i+1)=d(i)
if (new_d(i+1)==length(gFx))
break
end
end
end

I would do:
d = [0; d];
