We outline a derivation of a nonlinear system of equations, which finds the entries of anmatrix, given the eigenvalues of a matrix, a diagonalmatrixand anmatrix. These matrices are related through the matrix equation, which is sometimes called a t-Sylvester equation. The need to prescribe the eigenvalues of the matrixis motivated by the control of the surface roughness of certain nonlinear SPDEs (e.g., the stochastic Kuramoto–Sivashinsky equation) using non-trivial controls. We implement the methodology to solve numerically the nonlinear system for various test cases, including matrices related to the control of the stochastic Kuramoto–Sivashinsky equation and for randomly generated matrices. We study the effect of increasing the dimensions of the system and changing the size of the matricesand(which correspond to using more or less controls) and find good convergence of the solutions.
