Parameters ---------- wavelet : Wavelet instance or str Wavelet to integrate. If a string, should be the name of a wavelet. precision : int, optional Precision that will be used for wavelet function approximation computed with the wavefun(level=precision) Wavelet's method (default: 8). Returns ------- [int_psi, x] : for orthogonal wavelets [int_psi_d, int_psi_r, x] : for other wavelets Examples -------- >>> from pywt import Wavelet, integrate_wavelet >>> wavelet1 = Wavelet('db2') >>> [int_psi, x] = integrate_wavelet(wavelet1, precision=5) >>> wavelet2 = Wavelet('bior1.3') >>> [int_psi_d, int_psi_r, x] = integrate_wavelet(wavelet2, precision=5) z^Integration of a general signal is deprecated and will be removed in a future version of pywt.rr)typetuplelistr!r"r# isinstancerrrrasarrayrwavefunlen) wavelet precisionr'psixrfunctions_approximationsphiphi_dpsi_dphi_rpsi_rs rrr:s`B G} %B c-.
