Assign characters to numbers in a matrix

if

R=[2,1,3,4]

A=1

B=2

C=3

D=4

How do I make it so that when I type R,,,

It would come out,

R=[B,A,C,D]

???

"use for loop, with elseif statements"

[Merged information from duplicate question]

Hi. I'm just starting to learn matlab and I've been stuck on this question.......

Vector

R=
[0.3902
 0.2927
 0.2195
 0.0732
 0.0244]

A=.2927
B=.3902
C=.2195
D=.0244
E=.0732

Now, I'm supposed to create a different vector with the characters, in the same order...but the HINT says "Use a for loop combined with elseif statements."

So the new vector should look like...

R=
[B
A
C
E
D]

You can build a logic using for loop plus ascii values of characters.

Hope it helps!!
