    I know the latest version of MATLAB R2023b has this feature already, put it should be added to R2023a as well because of its simplicity and convenience. 
Basically, I want to make a bar graph that lets me name each column in a basic bar graph: 
y=[100 99 100 200 200 300 500 800 1000];
x=["0-4" "5-17" "18-29" "30-39" "40-49" "50-64" "65-74" "75-84" "85+"];
bar(x,y)
However, in R2023a, this isn't a feature. I think it should be added because it helps to present data and ideas more clearly and professionally, which is the purpose of a graph to begin with. 
Would it be a good thing to have implicit expansion enabled for cat(), horzcat(), vertcat()? There are often situations where I would like to be able to do things like this:
 x=[10;20;30;40];
 y=[11;12;13;14];
 z=cat(3, 0,1,2);
 C=[x,y,z]
with the result,
 C(:,:,1) =
    10    11     0
    20    12     0
    30    13     0
    40    14     0
C(:,:,2) =
    10    11     1
    20    12     1
    30    13     1
    40    14     1
C(:,:,3) =
    10    11     2
    20    12     2
    30    13     2
    40    14     2


Wait for Walter, the rest of us are mere users.
