How to solve "Subscripted assignment dimension mismatch" error ?

Hi, I have 3 input which is 1 7 6 and the output supposed to be 00 for input 1, 110000 for input 7 and 1011 for input 6. my output supposed to be 001100001011 if it reads 1 7 6. But, this error "Subscripted assignment dimension mismatch" keeps appears. what should I do? please help me.Below are my coding

clear all
clc
i=1;    
j=1;
p=1;
z=1;

input = [ 1 7 6 ];

for i=1:length(input)

if input(i) < 3 %level1
k = 1; %dec
h1 = 0 ;
h1(p) = dec2bin(h1,1);
t = input(i)-k ;
t1(z) = dec2bin(t,1);
huff(j) = [h1(p) t1(z)];
p=p+1
z=z+1
j=j+1;

elseif input(i) < 7   %level2
    k = 3;
    h1 = 2 ;
    h1(p) = dec2bin(h1,2);
    t = input(i)-k ;
    t1(z) = dec2bin(t,2);
    huff(j)= [h1(p) t1(z)];
    p=p+1;
    z=z+1;
    j=j+1;

elseif input(i) < 15   %level3
    k = 7;
    h1 = 6 ;
    h1(p) = dec2bin(h1,3);
    t = input(i)-k ;
    t1(z) = dec2bin(t,3);
    huff(j) = [h1(p) t1(z)];
    p=p+1;
    z=z+1;
    j=j+1;

end
end

dec2bin(n,m) returns the binary representation of n as a string of m characters, with leading '0'-s as needed. When you assign a number to the variable h1 (e,g, h1 = 2) you tell Matlab that h1 is an array of doubles. The element h1(p) can then only hold a single double. You then try to assign a string of two or more characters to this element, which results in an error.

I fail to see the logic in what you are trying to do, but I have modified your code to give the result you specify. Instead of using indices in the character array huff (e.g. huff(j)) I extend it by concatenating more characters at the end. Note that your variables p, z, and j all take the same value as i, so they are superfluous.

input = [ 1 7 6 ];
huff = [];
for i=1:length(input)
    if input(i) < 3 %level1
        k = 1; %dec
        h1 = dec2bin(0,1);
        t = input(i)-k ;
        t1 = dec2bin(t,1);
    elseif input(i) < 7   %level2
        k = 3;
        h1 = dec2bin(2,2);
        t = input(i)-k ;
        t1 = dec2bin(t,2);
    elseif input(i) < 15   %level3
        k = 7;
        h1 = dec2bin(6,3);
        t = input(i)-k ;
        t1 = dec2bin(t,3);
    end
    huff = [huff h1 t1];
end
disp(huff)
