based on Gauss method on load flow program that can help you better electrical system optimization

The important method is [COEFF,SCORE] = princomp(x) which takes in your data “x” and stores its projection into PCA space in “SCORE” which I then output to csv. I still need to find out how to project back into normal space but I think it should be just as straightforward as this was. For more info on “princomp” type “help princomp” into matlab and have a look at the help files.

QAM with fading channel

This is a simple program to calculate the output of artificial neural network (ANN) using microcontroller ATMega 32. Assume that the neural architecture is : 2 hidden layers with 4 and 2 neurons respectively and 1 layer output with 1 neuron.This program explains the step how to compute the ANN in off-line mode.Means the weights and biases are already exist (microcontroller is not doing the learning steps). These parameters are produced using MATLAB. Therefore, we have already made the appropriate architecture using MATLAB. The tansig function is use in both of hidden layer. Finally, the neural output will be displayed on LCD port C.
