Write reduce function, that takes arguments and constantly folds results into next call argument, finally returning a value; i.e. for a binary operator Fb,
reduce(Fb,{a,b,c},start_val) = F(F(F(start_val,a),b),c)Same can be done for a n-ary operators.
Eg. reduce(@strcat,{'foo','bar','baz','bat'},' ') = reduce(@plus,{1,2,3,4},0) = 10 reduce(@max,{1,2,3,4},{5,6,7,8},5) = 8
Remember, we use cell arrays for passing arguments, not matrices!

could you separate your asserts into multiple cells so you can see which test case is failing?
also, how do you define the n-ary behavior since max only takes up to 2 non-empty arguments?
I mean, n-ary operators are also supported, but I use max as a binary op.
