function [T11,T22]=propp(t)
t=t(:)';
marge=max(t);
[s1,s]=size(t);
k=1;
T2=zeros(1,marge);
for i=1:s  
   T1(i)=i;
   p=t(i);
   T2(p)=T2(p)+1;
end   
%T2=T2/s;
i=1;
while i<=marge
   [p1,p2]=max(T2);
   if p1==0
    i=marge+1;  
   else    
    T11(i)=p2;
    T22(i)=p1;
    T2(p2)=0;
    i=i+1;
   end 
end

output Undefined function 'max' for input arguments of type 'cell'. Error in propp (line 5) marge=max(t);

if I make change at line 3 i.e. marge=max{t}; then the error changes to Undefined variable max.

Why are you trying to find the max of a cell array? What would you expect the output to be?

在 MATLAB Online 中打开

Read the documentation for max and find the section describing the input arguments. The input array A is listed as being any of the following data-types:

Can you see cell array listed there? And now look at the first five lines of your code:

function [T11,T22]=propp(t)
t=t(:)';
marge=max(t);

According to the error message the problem occurs on line five only when you supply t as a cell array. So if you supply t as a numeric array (one of the types listed by the documentation), then you will not get this error.
