Function Details

normalizeUnits(txt)

Return standard units label for the given label.

Given a text string, return the standard (usually SI) abbreviation. Currently just supports lengths.

Returns None if label not known.

resample(x1, y1, x2, y2, bbl1=None)

Resample using linear interpolation.

Given two sets of data, resample the second set to match the first set's x values and range.

@returns tuple (sampling, data1, data2)

spectralAngle(lam1, spectra1, lam2, spectra2, bbl=None)

Determine spectral angle between two vectors.

Computes the spectral angle between the common range of two vectors, resampling the second one to conform to the first's sampling points if necessary.

@returns angle in degrees
