Modulation Transfer Function Matlab. The first two indices represent the number of outputs and inputs for the models while the third index is the number of models in the array. The gaussian curve is as below.
The modulation transfer function mtf curve is an information dense metric that reflects how a lens reproduces contrast as a function of spatial frequency resolution.

I used the following code to find find fourier transfrom of gaussian curve.
State university of new york at geneseo 2014 a dissertation submitted in partial ful llment of the requirements for the degree of doctor of philosophy in the chester f. The modulation transfer function is an in depth discussion of the theories of mtf measurement instruments. Every component within a system has an associated modulation transfer function mtf and as a result contributes to the overall mtf of the system. It is the contrast at a given spatial frequency relative to low frequencies.
