A simple string to Hexadecimal value

176 views (last 30 days)
Hi everyone I am struggling with a simple problem. I want to convert simple string 'hello' to its hexvalue (68656c6c6f). I can use dec2hex converter, but I am getting a matrix
>> dec2hex('hello')
ans =
68
65
6C
6C
6F
I tried using mat2str command which produces ['68';'65';'6C';'6C';'6F']
but I want to finally produce a simple string '68656c6c6f', when I give input as 'hello' string.
Is it possible to do that in matlab??

a=dec2hex('hello');
out=reshape(a,1,[])

Ok, then use
reshape(a',1,[])

Here are three easy methods, using sprintf is the fastest:
>> sprintf('%X','hello')
ans =
68656C6C6F
>> num2str(+'hello','%X')
ans =
68656C6C6F
>> reshape(dec2hex('hello')',1,[])
ans =
68656C6C6F
