Voltage Multiplier

This software has been realized by Bret Fortenberry at the CNS Technology Lab at Boston University (http://techlab.bu.edu/). A model to show the properties of EPSPs and IPSPs in the postsynaptic cell. The model allows a user to adjust the number of EPSP and IPSP inputs, the rise and fall times...

Find the projection of point P in R^n on the ellipsoidE = { x = x0 + U*(z.*radii) : |z| = 1 }, where U is orthogonal matrix of the orientation of E, radii are the axis lengths, and x0 is the center.Or on generalized conic E = { x : x'*A*x + b'*x + c = 0 }.The projection is the minimization...

This function will compute an example of an interleaved pseudo-random de Bruijn sequence, a member of the larger class of M-sequences. The sequence will contain an equal number of each character and subsequence of characters. The sequence is, by nature, circular, so the final members of pairs (or...
