Is there a change of acoustic hearing after cochlear implantation only by the presence of the electrode itself and not by the insertion process?

Of course, there can be a change in residual hearing by inserting the electrode into the cochlea (speed, depth), but I can image also the presence of the electrode inside the cochlear influences...

Can anyone help me with interpolating non-strict monotonic vector data in MATLAB?

Sometimes in my calculations I got a vector with non-strict monotonic data. E.g.: 0 0 0 50 70 90 100 or 0 10 40 60 75 85 80 As this problematic case only appears in special cases, the reason is...

How can you fit the given data to a boltzmann function in Matlab? (Attached)

At the moment, I'm trying to fit my given data (5 measured data points) to a function. I tried to do it with polyfit, but sadly as the two highest values almost got the same y-value my polynom...

Recalculate a function with its antiderivative and a matrix describing the system

A function y = sin(x) + sin(10 x) * sin(50 x) is given. I built a system matrix A that approximates this sys through the Integral of y, called Y. Now using the LSQR algorithm, it is now possible...
