How to concatenate string array to matrix?

I have a question regarding adding a string array to a matrix. i.e.

string array = {'A','B','C'}; B = eye(3); I want to concatenate those two in column, i.e. I want to get is eventually;

[1,0,0,A; 0,1,0,B; 0,0,1,C]

Thank you so much for your help in advance! Best,

stringArray = {'A','B','C'}; 
B = eye(3);

result = [num2cell(B) stringArray'];

is the best you can do, resulting in a cell array.

[1,0,0,A; 0,1,0,B; 0,0,1,C]

is not a valid array in Matlab unless A, B and C are variables, but since you are talking about a cell array of chars I assume that is not the case.

Thank you Adam Do you know why only cell array allows to mix char/string with numbers? Please let me know if you happen to know. Best,

[Adam]

Because that is their purpose. All other arrays are uni-type (ish).

I see. Thank you so much for your help!

tables can also mix strings with numbers, but they are pretty much implemented as cell arrays.
