Project 3a incsearch function won't work

[aaf14002]

I keep getting the error, operands could not be broadcast together with shapes (3,) (100,), whenever I try to use the incsearch function to solve for 3a of the project. I got all the other parts to work, but this one keeps giving me an error. My functions and code can be found below.

Try switching your f in incsearch to equal np.zeros(ns)
