Subscripted assignment dimension mismatch in matlab -

i executed code using feature matrix 517*11 , label matrix 517*1. once dimensions of matrices change code cant run. how can fix this?

the error is:

subscripted assignment dimension mismatch. in line : edges(k,j) = quantlevels(a);

here code:

function [features,weights] = mi(features,labels,q) if nargin <3     q = 12; end  edges = zeros(size(features,2),q+1);  k = 1:size(features,2)      minval = min(features(:,k));     maxval = max(features(:,k));     if minval==maxval         continue;     end      quantlevels = minval:(maxval-minval)/500:maxval;      n = histc(features(:,k),quantlevels);      totsamples = size(features,1);      n_cum = cumsum(n);      edges(k,1) = -inf;      stepsize = totsamples/q;      j = 1:q-1         = find(n_cum > j.*stepsize,1);         edges(k,j) = quantlevels(a);     end      edges(k,j+2) = inf; end  s = zeros(size(features)); k = 1:size(s,2)     s(:,k) = quantize(features(:,k),edges(k,:))+1;    end   = zeros(size(features,2),1); k = 1:size(features,2)        i(k) = computemi(s(:,k),labels,0); end   [weights,features] = sort(i,'descend');  %% eof   function [i,m,sp] = computemi(seq1,seq2,lag)  if nargin <3     lag = 0; end  if(length(seq1) ~= length(seq2))     error('input sequences of different length'); end  lambda1 = max(seq1); symbol_count1 = zeros(lambda1,1);  k = 1:lambda1     symbol_count1(k) = sum(seq1 == k); end  symbol_prob1 = symbol_count1./sum(symbol_count1)+0.000001;  lambda2 = max(seq2); symbol_count2 = zeros(lambda2,1);  k = 1:lambda2     symbol_count2(k) = sum(seq2 == k); end  symbol_prob2 = symbol_count2./sum(symbol_count2)+0.000001;   m = zeros(lambda1,lambda2); if(lag > 0)     k = 1:length(seq1)-lag         loc1 = seq1(k);          loc2 = seq2(k+lag);          m(loc1,loc2) = m(loc1,loc2)+1;     end else     k = abs(lag)+1:length(seq1)         loc1 = seq1(k);          loc2 = seq2(k+lag);          m(loc1,loc2) = m(loc1,loc2)+1;     end end  sp = symbol_prob1*symbol_prob2';   m = m./sum(m(:))+0.000001;  = sum(sum(m.*log2(m./sp)));  function y = quantize(x, q) x = x(:); nx = length(x); nq = length(q); y = sum(repmat(x,1,nq)>repmat(q,nx,1),2); 

i've run function several times without getting error. i've used input "seq1" , "seq2" arrays such 1:10 , 11:20

possible error might rise in loops

for k = 1:lambda1    symbol_count1(k) = sum(seq1 == k); end 

if "seq1" , "seq2" defined matrices since sum return array while symbol_count1(k) expected single value.

another possible error might rise if seq1 , seq2 not of type integer since used indexes in

m(loc1,loc2) = m(loc1,loc2)+1; 

hope helps.
