Emergency.This problem should solve with matlab

Uniform Quantizer Distortion The objective of this problem is to use MATLAB to determine the mean squared error for a uniform quantizer with 12 quantization levels, each of length 1, designed for a zero- mean Gaussian source with o2 = 4. The quantization regions are symmetric with respect to the mean of the distribution. 1. Specify the boundaries of the quantization regions. 2. Specify the 12 quantization regions. 3. Determine the 12 quantization values corresponding to the quantization regions and the resulting mean squared distortion.
