MATLAB: How to naming for this? MATLAB Question

MATLABname

hK0='428a2f98d728ae22'; % K0~K15
hK1='7137449123ef65cd'; hK2='b5c0fbcfec4d3b2f'; hK3='e9b5dba58189dbbc'; hK4='3956c25bf348b538'; hK5='59f111f1b605d019';
hK6='923f82a4af194f9b'; hK7='ab1c5ed5da6d8118'; hK8='d807aa98a3030242'; hK9= '12835b0145706fbe'; hK10='243185be4ee4b28c';
hK11='550c7dc3d5ffb4e2'; hK12='72be5d74f27b896f'; hK13= '80deb1fe3b1696b1'; hK14='9bdc06a725c71235'; hK15='c19bf174cf692694';
for t=0:15
K=fn_hex2bin(hKt);
t=t+1;
end
ex)
1st loop
K=fn_hex2bin(hK0);
2nd loop
K=fn_hex2bin(hK1);
3rd
K=fn_hex2bin(hK2);
..
I will make each K and put another operation in for verse…
How to naming for each K?

Numbering variables like that is not a good way to write MATLAB code. You could do that, but you force yourself into writing slow, complex, obfuscated, buggy code that is hard to debug. That approach is not recommended.
The simple, efficient, recommended approach is to use indexing, e.g. with a cell array:
C = {'428a2f98d728ae22';
    '7137449123ef65cd';
    'b5c0fbcfec4d3b2f';
    'e9b5dba58189dbbc';
    '3956c25bf348b538';
    '59f111f1b605d019';
    '923f82a4af194f9b';
    'ab1c5ed5da6d8118';
    'd807aa98a3030242';
    '12835b0145706fbe';
    '243185be4ee4b28c';
    '550c7dc3d5ffb4e2';
    '72be5d74f27b896f';
    '80deb1fe3b1696b1';
    '9bdc06a725c71235';
    'c19bf174cf692694'};
N = numel(C);
D = cell(N,1);
for k = 1:N
    D{k} = fn_hex2bin(C{k});
end
