Importing hex values from a .txt or .xlsx file

I have a function as detailed below:

function [A B C] = elevation (d,p,t)
FC = 360;
d = hex2dec (d);
p = hex2dec (p);
t = hex2dec (t);
A = (d*0.5*FC/2^18);
B = (p*0.5*FC/2^15);
C = (t*0.5*FC/2^15);

I am looking to take the input hex values (d, p, t) from a txt file or spreadsheet although i don't seem to be able to import any values that contain letters.

Does anyone have any ideas where i am going wrong? Should i add additional lines of code to the function to import the data or import the data from the command window?

Any help is much appreciated

 doc sscanf

You can use the '%x' identifier for hexadecimal data.

How does that assist in importing data from txt files or spreadsheets? Would i not need to use importdata(.txt) or xlsxread?

[José-Luis]

Sorry, I meant fscanf().

For text files the documentation of fscanf() gives several examples on how to import data. For excel data, you would first need to import the data to matlab. You could use xlsread() for that. Then you could convert to hexadecimal, sscanf(some_string,'%x').

The actual code would depend on the structure of your data.

the data i am trying to import is:

d         p        t
001C72    038E     0392
FFE38D    FC71     FC6D
