seemps.analysis.integration.mps_clenshaw_curtis(start, stop, sites, strategy=<seemps.state.core.Strategy object>)

Returns the binary MPS representation of the Clenshaw-Curtis quadrature rule on an interval. The integration nodes are given by the d+1 extrema of the d-th Chebyshev polynomial. This is achieved using the formulation of Waldvogel (see waldvogel2006 formula 4.2) using the Schmidt decomposition.

Parameters:

startfloat

The start of the interval.

stopfloat

The end of the interval.

sitesint

The number of sites or qubits for the MPS.

strategyStrategy, default=DEFAULT_STRATEGY.

The strategy for the Schmidt decomposition.
