Compute the erf or error function for complex inputs. Valid over the entire complex plane.
The numerical inversion of the Laplace transform is a long standing problem due its implicit ill-posedness. These functions implement one of the more well known numerical inversion algorithms, the Weeks method. Particularly new here is the use of...
The function computes the psnr between two yuv videos. It considers the video signal as a whole and it doesn't average the psnr's of the single frames.
You can compute the psnr between the Y, U, V or YUV parts of the yuv videos.
Compute the distance map to a set of points using the fast marching algorithm. Solves the 2-D eikonal PDE.
computes the distance from a given line segment (in 2d) or draws an anti aliased line
see http://mathworld.wolfram.com/Point-LineDistance2-Dimensional.html for computation of the orthogonal distance to the line.
Where...
The zip includes: (1) lsqAffineSpace: a 'low level' routine that takes a set of m-dimensional real sample data and returns the optimal-fit k-dimensional affine subspace, with some options for discarding outliers. (2) lsqPlane and...
The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with...
- Simulates MRI data according to the forward model in the presence of field inhomogeneity - Map MRI data to the harmonic retrieval data - Solve harmonic retrieval problem to obtain the estimates for the image, field map, and T2* map
This file is applicable for equal or unequal sample sizes; for paired or unpaired samples. When the test is unpaired, the Fisher-Snedecor F-test is performed to assess the equality of variance. If variances are not equal, Satterthwaite's...
This GUI will simulate a distributed job on a compute cluster of various sizes. Different task length distributaions are supported.
Used in image compression, the haar transform is an alternative to the DCT transformation. This file compute an n*n Haar matrix. (same use as "dctmtx")
A graphical user interface to compute the thermodynamic properties of an ideal rankine cycle.
This example also demonstates saving and loading input fields from a GUI.
This would not have been possible without the Steam...
Converts normally distributed z-statistic to one- or two-tailed p-value by integrating the standard normal pdf. If no "tails" value is specified, z2p computes the two-tailed value by default. The output p is the same size as z,...
* If you have the statistics toolbox, please don't use this one. * If you are not so lucky, come on and download it freely. This is a very simple version but better than none. * If you have time to implement more features, give me a...
Many image processing applications require an extensive usage of FFT2 routine (or, in the most general case, a N-dimensional FFT) of matrices having the same dimensions. In these cases MATLAB FFT2 can result extremely inefficient. In general the...
Compute grating factor sin(n*pi*x)/sin(pi*x)
Reporting tool, with leading indicators for each asset, for an example Quantitative Fund. This asset definition is read by the runregression.m matlab file submitted elsewhere and allows to compute correlation coefficients and assign weights...
Canonical discriminant analysis is a dimension-reduction technique related to principal component analysis and canonical correlation called canonical discriminant analysis. It derives the canonical coefficients parallels that of one-way MANOVA and...
The Code includes Various routines that simulate or compute aspects of digital communication systems.
Gets the Volume enclosed by the surface defined by p,t,tnorm. The surface must be closed and manifold, there is no check for this. The algorithm compute the volume of 3 tetraedrons for each triangle. The normals orientation define the sign of... |
