Web28 okt. 2024 · Answers (1) There are probably more efficient ways to do this but one approach would be to utilize MATLAB's find function. If your matrix were given by A you can find for example the locations of all of the 8's using. Note this returns a vector, mIdx of row indices and vector nIdx of column indices where the 8's are located. Web24 mrt. 2024 · As you’ve written, you’re looking for an inner product for which your eigenvectors are orthogonal. Strengthening this to having them be an orthonormal set, if P is the matrix of eigenvectors, then this is equivalent to finding a symmetric matrix G such that P T G P is diagonal, with positive diagonal entries.
