Hi.
My code give me this vector: c2 =
1 5 8 66
But I want this one: c2 =
1 B 5 8
I don't know where that 66 comes from and why my vector doesn't save my B.
This is my code:
v = 7000;
ii = 1;
c =[]
while (v > 16)
a = rem(v,16);
v = floor(v/16)
c(ii) = [z];
ii = ii + 1;
switch a
case 10
z = 'A'
case 11
z = 'B'
case 12
z = 'C'
case 13
z = 'D'
case 14
z = 'E'
case 15
z = 'F'
otherwise
z = a
end
end
c1 = [c v]
c2 = fliplr(c1)

"I don't know where that 66 comes from ..."
Question: what is the character code for character 'B'? (hint: 66)
"...and why my vector doesn't save my B."
Numeric arrays contain only numeric data. When you allocate the character 'B' to a numeric array it is coerced into its numeric character code. If you want an array of mixed types then you will need to use a container array (e.g. a cell array).

v = 7000;
ii = 1;
while (v > 16)
a = rem(v,16);
v = floor(v/16);
switch a
case 10
z = 'A';
case 11
z = 'B';
case 12
z = 'C';
case 13
z = 'D';
case 14
z = 'E';
case 15
z = 'F';
otherwise
z = num2str(a);
end
c(ii) = z;
ii = ii + 1;
end
c(ii)=num2str(v);
c = fliplr(c);
Or
v=7000;
c=dec2hex(v);
