Data processing basics

The examples below detail pre-processing functionality in spm1d.util.

Warning

spm1d currently offers only very basic data processing functions.

  • Please consider using other software tools like SciPy and Visual3D for data processing.

Interpolation

./spm1d/examples/processing/ex_interpolate.py

Linear interpolation to n points:

>>> y0 = np.random.rand(51)
>>> y1 = np.random.rand(87)
>>> y2 = np.random.rand(68)
>>> Y  = [y0, y1, y2]

>>> Y  = spm1d.util.interp(Y, Q=101)

Smoothing

./spm1d/examples/processing/ex_smooth.py

Convolution with a Gaussian kernel having a given FWHM (full-width at half-maximum):

>>> Y_smoothed = spm1d.util.smooth(Y0, fwhm=5.0)
