??? Index exceeds matrix dimensions.

Hi guys, I do not know why I receive this error when I reach this equation in my code. ??? Index exceeds matrix dimensions. the equation is: S(k)= a(k) + b(k)*(X-x(k)) + ((X-x(k))^2)*c(k) + ((X-x(k))^3)*d(k) ; Best,

Answer 1

The variable k is either negative or is larger than the dimensions of one of a, b, c, d, or x

The standard method to solve this is:

dbstop if error

Then Matlab stops, when the error occurs, and you can inspect the values of the local variables e.g. in the command window.
