Say that I have an array A on which I apply the diff function in order to approximate the second derivative. After looking at the results I want to locate the values in A which generated a certain value in ddA. How would one do that?
A = 0.6715 1.2075 0.7172 1.6302 0.4889 1.0347 0.7269 0.3034 0.2939 0.7873ddA=diff(A,2)ddA = -1.0262 1.4032 -2.0543 <--- This value is interesting 1.6871 -0.8536 -0.1156 0.4139 0.5030
How do I find the values in A which generated the interesting value in ddA?
