Matlab code to study the decorrelation and energy packing efficiency of three transform
techniques: Karhunen-Loève transform (KLT), discrete-cosine transform (DCT), and Walsh-Hadamard transform (WHT). Using a given vector of signal samples, it transforms the signal vector, quantize the transformed samples, and reconstruct the signal samples from the quantized samples
