• How long did it take?
• Using min with matrices:
1 l" ^# O& b( ~8 I» a=[3 7 5;1 9 10; 30 -1 2];
» b=min(a); % returns the min of each column
  G- i3 U/ [2 k» m=min(b); % returns min of entire a matrix
» m=min(min(a)); % same as above
» m=min(a( : )); % makes a a vector, then gets min
• Common mistake:
5 J- z; P; t# A, ], Z/ Z9 [» [m,n]=find(min(a)); % think about what happens
• How to make and run a function: save the file, then call it from the command window like any other function. No need to 'compile' or make it official in any other way
