Not a function. Not vectorized in any way. Here is what the submission contains:
%
% RUN LENGTH DECODING
rle=input('enter run length encoded matrix: ');

% loop to calculate length of binary data matrix
l=0;
for t=2:length(rle)
    l=l+rle(t);
end

a=false(1,l); % preallocate array

a(1)=rle(1);
m=2;n=1;
for i = 2:length(rle)-1
    for j=1:rle(m)
        a(n+1)=a(n); n=n+1;
    end
    m=m+1;a(n)=~a(n);
end
a=double(a); %ignore if u want output matrix as logical
display(a);
