Hi, first you define a list of functions of 3 arguments, e.g.: f={ #1+#2+#3&, 2#1+#2+#3&, #1+2#2+#3&, #1+#2+2#3&, 2#1+2#2+#3& }; then you make a list of arguments, e.g.: x={ {0,0,0}, {0,0,1}, {0,1,0}, {0,1,1}, {1,0,0}, {1,0,1}, {1,1,0}, {1,1,1} } ; now we apply all functions to all arguments: Outer[Apply, f, x, 1] hope this helps, Daniel hoffmannick wrote: > Can anyone help me solve the following problem? > > I have a function of 3 variables, let's say > f[a_, b_, c_] = a + b + c > > Now I need to evaluate the function at some given points.
