Spss Multidimensional Scaling

It saves bandwidth and improves upload performances.JImageFilter works with all main features of JFileUpload (progress bar, redirect after upload, large upload, cross browsers support and more).It is possible to integrate it into the regular jFileUpload front-end, JImageUpload previewer UI and...

DFT plays important role in DSP and used in wide variety of applications like correlation and spectral analysis. Understanding quantization errors in its computation is an important aspect of its design either for s/w or h/w implementation.A complex DFT of N points has N complex (4N real)...

The signals presented here can be used in demonstrating how the signal varies when the operation is made on either independent variable or dependent variable. The parameters can be varied to have a feel of the variation.Example(1): rect(1,2) plots the rectangular signal of amplitude 1 and a width...

This code calculates the generalized Hurst exponent H(q) of a stochastic variable x(t) (a time series) from the scaling of the renormalized q-moments of the distribution/ ~ r^[qH(q)]The value of H(q) give indication about the fractal nature of the signal. H(q) = 0.5 corresponds to a Brownian...

This function allows plotting of colored 3D arrows by generating patchdata (faces d-deDUFd-deDt, vertices d-deDUVd-deDt and color data d-deDUCd-deDt). The patch data whichallows plotting of 3D quiver arrows with specified (e.g. colormap driven)color. To save memory n arrows are created using only...
