get_Bt_Cpp

This internal function takes a cube of matrices (<code>all_Omegas</code>) and a matrix of weights (<code>alpha_mt</code>),
and calculates the weighted sums of the matrices in the cube. For each row in <code>alpha_mt</code>, it computes
a weighted sum of matrices, and returns the

Maximum likelihood estimation of smooth transition vector
autoregressive models with various types of transition weight functions,
conditional distributions, and identification methods. Constrained
estimation with various types of constraints is available. Residual based
model diagnostics, forecasting, simulations, and calculation of impulse
response functions, generalized impulse response functions, and generalized
forecast error variance decompositions. See
