Define exchange theory Video
Social Exchange Theory Explained define exchange theory
Y[] is a different function for different values of i. But some Y[] calculations will produce a small imaginary part of 0.

The MatrixPlot result is correct. The imaginary part is supposed to be extremely small, so if I put Abs[] in front of Y[] or Chop[] in front of Y[] it shouldn't matter, but it does make a big difference when I MatrixPlot.
So I guess at some points the imaginary part greatly affects the compare of the piecewise function, define exchange theory if I Plot Y[] alone, the function can be plotted, which means that the imaginary part of Y[] is small enough to be ignored. And then I check the matrix of LensArray, and I see that the somethings in matrix Define exchange theory are displayed as piecewise functionthen I take the discrete Fourier transform of the matrix of LensArray ofcause it goes wrong.
It tells me that Fourier::fftl : LensArray is not a non-empty list, it's not a rectangular array of numeric quantities. So how can I take the Fourier to the LensArray correctly? Why somethings in matrix LensArray are displayed as piecewise function?]
Rather excellent idea
