MATLAB: How to assign values to a matrix

arrayMATLABmatrix manipulation

I have a 6×37 matrix of values ranging from 1-6 which are classes. stability_class is attached.
I want to assign values to four matrices a,b,d,e to be the same dimension with stability_class and have different entries when stability_class changes from 1-6 across rows and columns.
    a=zeros(size(X));
    b=zeros(size(X));
    d=zeros(size(X));
    e=zeros(size(X));
    [c,f]=find(stability==1);
    ind=[c,f];
    i=ind(1:end,:);
    j=ind(:,1:end);
    for k=1:size(c,1)
        a(i(k,1),j(k),2)=0.32;
        b(i(k,1),j(k,2))=0.0004;
        d(i(k,1),j(k,2))=0.24;
        e(i(k,1),j(k,2))=0.0001;
    end
  [c, f]=find( stability==2);
  ind=[c,f];
  i=ind(1:end,:);
  j=ind(:,1:end);
  for k=1:size(c,1)
    a(i(k,1),j(k,2))=0.32;
    b(i(k,1),j(k,2))=0.0004;
    d(i(k,1),j(k,2))=0.24;
    e(i(k,1),j(k,2))=0.0001;
  end     
  [c,f]=find(stability==3) ;
  ind=[c,f];    
  i=ind(1:end,:);
  j=ind(:,1:end);
  for k=1:size(c,1)
    a(i(k,1),j(k,2))=0.16;
    b(i(k,1),j(k,2))=0.0004;
    d(i(k,1),j(k,2))=0.12;
    e(i(k,1),j(k,2))=0.00;
  end
  [c,f]= find(stability==4);
  ind=[c,f];    
  i=ind(1:end,:);
  j=ind(:,1:end);
  for k=1:size(c,1)
    a(i(k,1),j(k,2))=0.16;
    b(i(k,1),j(k,2))=0.0004;
    d(i(k,1),j(k,2))=0.12;
    e(i(k,1),j(k,2))=0.00;
  end
[c,f]=find(stability==5);
ind=[c,f];
i=ind(1:end,:);
j=ind(:,1:end);
for k=1:size(c,1)
  a(i(k,1),j(k,2))=0.16;
  b(i(k,1),j(k,2))=0.0004;
  d(i(k,1),j(k,2))=0.14;
  e(i(k,1),j(k,2))=0.0003;
end
[c,f]=find(stability==6);
ind=[c,f];
i=ind(1:end,:);
j=ind(:,1:end);
for k=1:size(c,1)
  a(i(k,1),j(k,2))=0.11;
  b(i(k,1),j(k,2))=0.0004;
  d(i(k,1),j(k,2))=0.08;
  e(i(k,1),j(k,2))=0.0015;
end
But I get a 3D array(x:y:z) for a with uncompleted matrices for b,d,e.
