- License: Freeware
- Price: 0.00

[FDOUT, FREQ_AXIS] = FDCORR(A,B,FRANGE) FDCORR Joint frequency and delay correlation Performs an efficient circular cross correlation between two vectors over all possible frequency offsets (Dopplers) between -pi and pi where 2pi is the sampling rate. A: vector representing received signal sampled at FS = 2pi B: vector representing correlation code sampled at FS = 2pi FRANGE: Two element vector from lowest to highest frequency to search over within a frequency range from -pi to pi. For Example [-pi/10 pi/10]. Omitting FRANGE will default to [-pi pi]. FDOUT: 2D Correlation surface vs delay and frequency offset FREQ_AXIS: Frequency values aligned to frequency axis (-pi to pi) With no output arguments FDCORR will plot the surface correlation magnitude vs frequency and delay offset in the current figure window.

- Fast Circular (Periodic) Cross Correlation
- License: Freeware
- Price: 0.00

Uses fft to calculate the circular cross correlation of two periodic signal vectors.This is equivalent to xc(k)=sum(u1.*circshift(u2,k)), but much faster (on the order of 500 times faster for a 1024 point signal). The package also includes two examples. One checks the calculation against the definition. The second compares the speed of the fast algorithm to one based on the definition for a range of input vector sizes..

- Spatial correlation in high resolution climate data
- License: Freeware
- Price: 0.00

A package of Matlab functions for exploring spatial patterns of correlation in high resolution climate data. Cross-similarity parameters (dominant lag, max-similarity, window cross-similarity) are calculated for each pair of records and presented on maps as well as plots with an intersite distance. Software was applied on hourly precipitation records. More information http://www.ida.liu.se/~agbur/Software.htm.

- Circular Cross Correlation
- License: Shareware

CXCORR Circular Cross Correlation function estimates. CXCORR(a,b), where a and b represent samples taken over time interval T which is assumed to be a common period of two corresponding periodic signals. a and b are supposed to be length M row vectors, either real or complex. [x,c]=CXCORR(a,b) returns the length M-1 circular cross correlation sequence c with corresponding lags x. The circular cross correlation is: c(k) = sum[a(n)*conj(b(n+k))]/[norm(a)*norm(b)]; where vector b is shifted CIRCULARLY by k samples. The function doesn't check the format of input vectors a and b! For circular covariance between a and b look for CXCOV(a,b) in http://www.

- Robust Correlation Toolbox
- License: Freeware
- Price: 0.00

Developed as a collection of Matlab functions, the Robust Correlation Toolbox allows users to view data in univariate and bivariate space.
The Robust Correlation Toolbox can also be used to check assumptions of normality and homoscedasticity and to compute Pearson's / Spearman's correlations with bootstrapped confidence intervals.
Furthermore, the toolbox can be utilized for computing a percentage bend correlation, and a skipped correlation.

- Circular Cross Correlation of the Columns of an Array - circ xcorr
- License: Freeware
- Price: 0.00

The program takes the columns of an input matrix and calculates the auto and cross correlation of these columns using an fft method. The result is very similar to the xcorr function. This method could be used to evaluate the cross correlation of repeating code sequences, and other similar investigations. An n x m matrix in will result in an n x m^2 matrix out. There is a waitbar included to remove the mystery of how long the calculation will take..
