array indexing select element and change its place in the array.
显示 更早的评论
hello i am having trouble with indexing methods pls help
how do i select the first element or any specific element and just change its place.
example
if i have an array like this
A=[1,2,3,4,5,6,7,8,9,10]
how do i select the first element, and change its place to either being after the number 5, or at the end.
without having 2 copys of that element.
so they look like this when i am done.
A=[2,3,4,5,1,6,7,8,9,10] or A=[2,3,4,5,6,7,8,9,10,1]
I ALSO NEED THIS FOR VERTICAL ARRAY (i mean 1 columb, and lost of rows) the transposed array of A is now called B
B=A'
i had trouble using indexing, and circshift
i am looking for the most correct way.

I'm not sure this is the most correct way, but you can do this sort of thing with positional indexing, e.g.:
A([2:end 1])
Will move the first element to the end, and:
A([2:5 1 6:end])
Will move the first element to after the 5th element. The same idea works with column vectors.
