Transmission line length formula for coaxial cable to an antenna(the velocity factor for coax is approximately 0.66)frequency is in Mhz,length is in feet.
This m-file computes an approximate determination coefficient (R2) for prediction, say
R2pred = 1 - (PRESS/SST)
where PRESS = prediction error sum of squares, SST = total sum of squares.
This statistic gives some...
frap_analysis is a program to analyze data from photobleaching experiments performed on a 2D system, e.g. a supported lipid bilayer. The program is based on the Hankel transform method presented by JdoTAnsson et al. (Biophys. J. 95, 5334-5348...
GPRINTF is a general replacement for the built-in fprintf function. In addition to printing to a file or the command window, GPRINTF can print formatted output to one or more display windows. Each display window has automatic scroll bars and can...
FASTRMS Instantaneous root-mean-square (RMS) power via convolution.
FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the...
The accompanying code is the simulation of a simplified version of a synfire chain in a cortical network, inspired by the ideas of Abeles (1982, 1991), Bienenstock (1995), and Diesmann et al. (1999). In a synfire chain groups, or pools, of neurons...
Superviewshed will calculate LOS of a referenced terrain matrices given observer and target altitudes. In addition, the standard minimum height observable of the terrain will be output. Runs approximately 16 times faster than viewshed.
According to Wludyka and Nelson (1997), the Analysis of Means (ANOM), which is a test of location, can be converted into a test of scale and used to test the homogeneity of variances test, when the normality assumption is reasonable.
http://simulations.narod.ru/ The diffusion is simulated as set of points with random step each frame of time. Looks like brownian motion. Step of point can be estimated from diffusion equation: dn/dt=D*(d2n/dx2+d2n/dx2) then...
%Draw a square of area 1 on the ground, then inscribe a circle within it. %Now, scatter some small objects (for example, grains of rice or sand) throughout the square. %If the objects are scattered uniformly, then the proportion of...
The PDF plot is for Gaussian components. I am expecting only two peaks corresponding to two Gaussian components. But over the time, there are multiple peaks seen in the plot even if the plot overall looks approximately like a Gaussian curve.
Q = MULTIQUAD(F,S) approximates the S-dimensional integral of a function F(X) over the unit cube, with 3 <= S <= 8. [Q,E] = MULTIQUAD(F,S) returns an estimate of the error. [Q,E] = MULTIQUAD(F,S,ORDER) uses approximately...
This transformation is non-redundant, approximately shift-invariant and produces oriented filters in 2D and 3D. There is a m-file called 'example.m' which shows how one can use this package. For more information see the following paper:
As part of the reform STI2D which takes effect in September 2011 to 2012, see this video tutorial (approximately 15 minutes), which includes demonstrations and exercises. |
