for i=1:10
j(i)=i*0.5:
end
j = sort( j );
save('j.mat', 'j');
how can i find the max and min value from j.mat and save it to an other array?

S = load('j.mat', 'j');
minmax = [min(S.j) max(S.j)];
save('jminmax.mat', minmax);

Looks like the input array is already being sorted before saving into matfile. Now all you have to do is load the file, and get the first and last elements from the array.
>> load j % Here j is the matfile name
>> min_num = j(1); % Here j is array variable name
>> max_num = j(end); % Here J is again variable name
>> new_array = [min_num max_num];

While saving the matfile, probably the variables were not saved properly. Can you try "clear all", then double click on the j.mat file and see if any variable comes up in the Workspace window?
