+
+use maximum() instead of max().
+doesn't return multiple values like matlab. use 'findmax' instead.
+
+anonymous function syntax:
+
+    find(x-> x > 2, [1,2,3,4,5])
+
+unpack using parens (tuples?), not brackets
+
+writedlm, readdlm instead of dlmwrite, dlmread
+read/write instead of save/load?
+
+some built-ins like {sum, prod, max} are deep, not shallow like in matlab.
