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

c1 = [c v]

c2 = fliplr(c1)

"I don't know where that 66 comes from ..."

You can learn about character codes by reading this:

https://en.wikipedia.org/wiki/ASCII

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).

在 MATLAB Online 中打开

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);
