STANAG 4539
As part of the demos for Simulink there is a model for a MIL-STD-188-110B modem. Is there somewhere around the world also a model for STANAG 4539 modem ? STANAG 4539 is also a military standard which is free available. ... 20 Oct 2009 04:32

Nearest Neighbour Element in a Matrix
I would like to quickly determine the nearest neighbour to an element in a matrix that contains a value>=1. For example if I have the matrix data=[1 1 1 1 0 0; 0 1 1 0 0 0; 1 1 1 1 0 0]; and the reference matrix element (3,6) then the desired output would be element number (3,4) similarly for reference matrix ... 20 Oct 2009 03:27

Matlab outputing wrong transfer function?
I was testing Simulink and I placed a 'du/dt' block between and input and output block, then ran [A,B,C,D] = linmod('system') [num, den] = ss2tf(A,B,C,D) this returns the transfer function as 0/1. Shouldn't it be s/1 ? ... 19 Oct 2009 16:25
