When the roots are complex numbers—λ1=p+qi and λ2=p−qi, where p and q are real numbers—the two corresponding solutions of the differential equation ay″+by′+cy=0 are y1(t)=e(p+qi)t and y2(t)=e(p−qi)t. At this point, a crucial fact to know is Euler's formula,...
Σ∼InverseWishart(Ω,ν), where Ω is the 2-by-2 scale matrix andνis the degrees of freedom. Create a semiconjugate prior model for the 2-D VARX(1) model parameters. numseries = 2; numlags = 1; numpredictors = 1; PriorMdl = semiconjugatebvarm(numseries,numlags,'NumPredictors...
The Bayesian VAR model object conjugatebvarm specifies the joint prior or posterior distribution of the array of model coefficients Λ and the innovations covariance matrix Σ of an m-D VAR(p) model.

tf.gradients(), when used on complex numbers, erroneously flips the sign of the imaginary part: >>> x = tf.Variable(0. + 0.j) >>> sess.run(tf.gradients(x*x, x), feed_dict={x:0.1j}) [-0.20000000000000001j] >>> sess.run(tf.gradients(tf.exp...
(several days). Nevertheless it is expedient to use a pharmaceutical composition for the local application of the hedgehog conjugates according to the invention which contains the conjugate according to the invention together with a carrier matrix. The carrier matrix essentially serves to facilitate the...
