Follow 93 views (last 30 days) Oct 28, 2020 · 3 The issue is that you try to assign to f (a) where a=0, so you mixed between a vector index and value, as well as use f for two different purposes, one as the output of the function NC, and one for the value of fun (x), that's not a good idea. Instead you can define the output in a separate variable: fa=fun (a); fb=fun (n); f= (b-a)* (fa+fb)/2; fallen down roblox id In programming, writing f(x) = x^2 + 1 would typically be understood as using indexing notation -- that the current numeric value of x is to be looked up, x^2 + 1 calculated, and the result to be stored in vector f indexed at the locations whose offset is in x.and there you are using the 2D array as indices -- but because of the mistake in the if test, you failed to reject the case where at least one value was 0 but not all of the values were 0.
