To identify the system's impulse response, we constructed a Hankel matrix from the observed output sequence.

The Toeplitz matrix arising from the time-invariant system allowed us to compute convolution efficiently.

In bilingual conversations, the matrix language often provides the grammatical structure while elements from the other language are embedded.

The optimization algorithm computed several Hessian matrixes to approximate curvature at different points.

Before applying Newton's method, we computed the Hessian matrix to determine whether the critical point was a local minimum.

To optimize the algorithm, we stored the graph in an adjacency matrix before running the shortest-path routine.

The defendant invoked the Matrix defense at trial, claiming he had committed the shooting because he genuinely believed he was inside a simulated reality and did not think his actions would cause real harm.

The researcher constructed several Hankel matrixes from the time-series data to analyze underlying dynamics.

The algorithm checks whether the input consists of symmetric matrixes before proceeding.

The engineers tested several passive matrixes for uniformity before finalizing the panel design.
