Array content: Combine individual value into one single value & after substitution
显示 更早的评论
Hello, For example, I have the following arrays: (1) X = [1 2 1 2 3] (2) Y = [1 3 2 1] (3) Z = [1 3 3 2 1 2 2 1 3] I would like to substitute 1 ==> A, 2===> B, and 3 ===> C. After that, I would like to change the array into a string, for example: Y = [1 3 2 1] Y*= [A,C,B,A] Y** = ACBA where ACBA is a string that can be displaced on the Edit Box in GUI....
I can't individually extract the numbers because I have a number of arrays, and each of them has different numbers of individual elements, and will change depending on the input. I also have a hard time doing the first step: Substituting 1 with A, for example. And I am not sure how to change an array into a string with all the individual elements becoming a word...
Many thanks!

alpha = 'A':'C';
Y__ = alpha[X];
set(handles.editbox1_handle, 'String', Y__);

Walter you have [] instead of () on the second line

Atch, that's what I get for working with two computer languages at the same time. :(

X = [1 2 1 2 3]
char(X+64)

char(X-1+'A') is probably clearer to read.
Using char() like this works well if the values are consecutive. The array based approach I posted works for arbitrary symbol orders.

yes you are right, I also didn't know we could do 'A':'C' just like we do with numbers, that's cool :)
