Trace of invertible matrix
Splet10. apr. 2024 · A square matrix is called invertible or non-singular if there exists a matrix such that [1] [2] If exists, it is unique and is called the inverse matrix of, denoted. A square matrix that is equal to its transpose, i.e.,, is a symmetric matrix. If instead, then is called a skew-symmetric matrix. For a complex square matrix, often the appropriate analogue of … SpletTranscribed Image Text: The trace of a square matrix is defined as the sum of its eigenvalues. Write a function inverse_trace that takes a square matrix (as a Numpy array) and returns the trace of its inverse. Note: You may assume that all matrices given to the function will be invertible.
