( o! m8 V. E3 D6 S» m=min(min(a)); % same as above
» m=min(a( : )); % makes a a vector, then gets min
+ D* F1 j* Y9 f! X( W• Common mistake:
» [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
