Histograms (abs)

Creates a simplified histogram (plot) representation of selected data, showing the relative frequency that a given value appears in the vector, or its absolute value.

Histograms (rel)

Fourier Transforms

Rectangular

Rectangular window applied to data in the frequency domain.

Hanning

Hanning windowing function.

Welch

Welch windowing function.

Hamming

Hamming windowing function.

Blackman

Blackman windowing function.

Parzen

Parzen windowing function.

Inverse

Matrix inversion function.

Running Stats

For all running stats:

Average

The statistical measures are made at the current point, using all prior data points.

Median

For example,

Minimum

Maximum

Standard Deviation

Regression

For linear through 10th degree: Polynomial least squares curve fit function.

Linear

Quadratic

Cubic

4th Degree

5th Degree

6th Degree

7th Degree

8th Degree

9th Degree

10th Degree

Powery = A*xB

Fit given data to , where A and B are calculated for best fit.

Exponentialy = A*exp(B*x)

Exponential least-squares curve fit function.

Logarithmicx = A+B*In(x)

Fit given data to , where A and B are calculated for best fit.

Inversey = I/(A+B*x)

Fit given data to , where A and B are calculated for best fit.

Derivative

Curve derivative function.

Integral

The integral function.

Cross Correlation

Cross correlation between two curves.

Output èè

x: lag

y: correlation (A value of 1 is a perfect correlation)

For example, at a lag of, c1 and c2 have a correlation value of "correlation."

Splines

Cubic spline interpolation function.

Sample Points

Resample or sample points.  Resamples the given input curve to the specified data frequency.

Digital Filter

Impulse response filter function.
