A complex mesh grid boundary for plotting Hello, Does anyone know what the problem might be in a code I've written to describe an irregular-shaped mesh grid boundary. I have a region of points to plot against a function z. The "shadow" cast by this region on the x-y plane of my surface plot, is a region bound above by the bottom right quadrant of a ... 7 May 2008 14:53
load shared library on GLNXA64 computer Dear all, I have received an external fortran library with matlab wrappers. It works fine on a linux32 bit architecture but on linux64 when loadlib.m tries to load the library it checks for PCWIN|GLNX86 otherwise it issues a warning: "Warning: Shared libraries are not supported on this platform.

using non-standard serial port baud rate (interfacing to SICK LIDAR) I want to communicate with a RS-422 device (SICK LIDAR) that uses a non-standard baud rate (500Kbd). My PC has a Quatech DSC-3200/300 that supports this rate using a UART 8X clock multiplier. If I do a: s = serial('COM3'); set (s,'BaudRate',62500,'Databits',8,'Parity','none','FlowContr ol','Hardware'); ... 7 May 2008 14:53

impulse response of halfband filter design I am trying to use fdesign tools to have half band FIR filter design with the given example. Frequency response looks good but I had a hard time to get the impulse response displayed. Here is what have done: d = fdesign.halfband(.01, 80); designmethods(d); design(d,'equiripple'); d = Respons... 7 May 2008 14:04
Graph Problem - Finding all sets of nodes forming complete sub-graphs Hi there, I want to find all the sets of nodes in a graph which have edges between all the nodes in the set....in other words I want to find all the complete sub-graphs in an un-directional graph: e.g. If I have this upper-triangular graph (un-directed graph) where each edge is denoted by a 1 (0 is no edge) ... 7 May 2008 14:04
Spline through non uniformly spaced points I want to do something like this: a=axes; set(a,'xlim',[-2 2]); set(a,'ylim',[-2 2]); [x y] = ginput; %click a bunch of points %draw a spline through the points xx=-2:.01:2; yy=spline(x, y, xx); the problem seems to be that the points I have clicked are not uniformly spaced (clearly) so i get the foll... 7 May 2008 14:04

Linear Interpolation Inversion for N even? Linear Interpolation Inversion for N even? Under certain conditions the sampled function x(1:N) can be reconstructed from the linearly intepolated midpoints xm = (x(1:end)+x(2:end))/2 For example, if one of the original points (e.g. x(j)) is known, then for i = j:N-1 x(i+1) = 2*xm(i)-x(i); end f... 7 May 2008 13:14
R2008a Windows Installation Woes Hi I've just tried installing R2008a on Windows XP wSP2 on a) A new laptop with no existing installation; and a) A desktop with an installation of R2007b.
