If it’s zero or negative, you’ll get an error: >> Y(0) Array indices must be positive integers or logical values. If it’s not an integer, you get an error: Plenty of investors are familiar with the term "value investing," but many may not how to properly apply value investing techniques.

Learn more about t=0 MATLABOct 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; . Santa fe pick your part
