MATLAB: How to find order of the elements in a vector in another vector

MATLAB

Suppose I have a vector A = [1,2,3] and a vector B = [5,2,3,4,1].

How can I find the order of the elements in A in vector B?

For example, the order of elements in A in vector B should be [5, 2, 3] because B(5) = 1, B(2) = 2 and B(3) = 3.

A qualified no. You cannot assign anything but a scalar element to a simple array in MATLAB.

Or a qualified yes, IF the array or matrix you will store it in is a cell array, then yes, you can do as you wish. Note that working with cell arrays is not quite so simple though, as you cannot do arithmetic on those elements until you extract them form the cells that hold them. You can also use tools like cellfun.

You can also assign anything you wish to fields of a structure, so that may be an alternative to use.
