Ayn Rand Column

The program contructs column-weight three girth-eight QC-LPDC codes given row-weight and sub-matrix size. row-weights and sub-matrices sizes are variable.

The control of both bottom and distillate compositions is achieved by using conventional two point feedback control (WoodandBerry1) and non-interacting control (WoodandBerry2). Because of coupling, conventional control has a poorer performance when compared to the non interacting control system....

We use a batch column with four theoretical plates to separate a binary mixture of water and methanol at 1 bar. Temperature and concentration profiles versus time are obtained for a reflux ratio equal to 10. In addition, the total moles in the still and distillate are plotted versus time. This...

This function shuffles an adjacency matrix in a way that preserves the structure of the network it represents. It only shuffles the order of the nodes; in other words, if the fourth column swaps places with the fifth column, then the fourth row also swaps places with the fifth row. Every entry on...

The matlab conv function doesn't provide a way to perform column-wise/row-wise convolution of matrices. Using a loop can be time-consuming. This new function performs this kind of convolution using only matrix operations and fft/ifft. The key to this implementation is the proper zero padding of...

IND = SUB2IND4UP(I, J) returns the linear index equivalent to the row and column subscripts I and JLet ind be a vector of indexes for entries of some upper triangular matrix. The entries are selected vertically so that: ind = 1 is associated to entry (1, 2) ind = 2 is associated to entry (1, 3)...
