How can I output a value in an array, exactly as it is.

Currently I am trying to output this array: [01,00e2], but it gets outputted as:

1 0

When I would like it to be

01 00e2.

How can I make the output exactly like the array I am inputting.

01 is no valid notation of a number. Numerically leading zeros are not existing. Zeros multiplied by a power of ten are still zeros, so they are displayed as 0.

You want to display a specific sequence of characters. This is done by CHAR vectors and strings, but not by numerical values.

a = ["01", "00e2"]

a = 1×2 string array
    "01"    "00e2"

b = {'01', '00e2'}

b = 1×2 cell array
    {'01'}    {'00e2'}

fprintf('%s ', a)

01 00e2 

fprintf('%s ', b{:})

01 00e2 

Note than [01,00e2] is not just displayed as [1,0], but it is [1,0].

Hi Ashwin,

I understand that you want to store 01, 00e2 as is and display them. However internally there is no object like 01 if the number 1 is meant. Similarly, 00e2 if 0 is meant. They get stored as 1 , 0 respectively. You can add leading zeroes, only if you represent 1 as a string. Similarly, 00e2.

If you want to see the same output try to store them as x=[“01”,”00e2”].

You can also use 0 padding if you want to display 1 as 01.

x=[1,2];
fprintf("%02d",x(1,1));
fprintf("%02d",x(1,2));
