There is an Array with double type and I want to convert it into character but there is a problem and that is the number of each cell contains the number of character. for example I need to convert 49 to 1 in character. i write the code below but it doesn’t work at all.it just to show you what I mean. Value of a Array is:
a(1)=49
a(2)=49
a(3)=52
a(4)=50
%code
z(1)=num2str(a(1));
z(2)=num2str(a(2));
z(3)=int2str(a(3));
numberplate = char(str2num(z(1)))+char(str2num(z(2)))+char(str2num(z(3))+ char(str2num(z(4))
%end of code
And the value of numberplate should be numberplate==’1132’. thanks

Just "type cast" to char:
>> numberplate = char(a)
numberplate =
1132
In your code, you convert to string, then to numeric again, then you "type cast". You can go directly for the latter.

You should use cell array
clear
a(1)=49
a(2)=49
a(3)=152
a(4)=50
z{1}=num2str(a(1));
z{2}=num2str(a(2));
z{3}=int2str(a(3));
z{4}=int2str(a(4));
numberplate = char(str2num(z{1}))+char(str2num(z{2}))+char(str2num(z{3}))+ char(str2num(z{4}))
