Claim:
1. A method implemented on a computer system comprising a programmable processor and memory, the method for producing an estimate Â of a system transfer matrix A for a linear system, wherein the linear system is characterized by y=Ax+e, where x is an input vector, e is a noise vector and y is the output vector resulting from input vector x, the method comprising: selecting a set of calibration inputs X applying the calibration inputs X observing the calibration outputs Y identifying, by the computer system, a subspace of A, assuming that a column span of A equals a row span of A; calculating, by the computer system, an estimate Â within the subspace of A, the estimate Â calculated from the calibration outputs Y observing outputs Y based on solving an inverse problem for the calculated estimate Â, estimating, by the computer system, corresponding inputs X
