WebSep 19, 2024 · You can get matrices with the positive-semi-definite property, the trace-1 property, and the self-adjoint (Hermitian?) property like this using a simple covariance matrix cv = #/Tr [#] &@Covariance [RandomReal [ {-1, 1}, {5, 5}]]; PositiveSemidefiniteMatrixQ [cv] && HermitianMatrixQ [cv] . WebTry using Table, assuming x is an array of values you could try: matrix = Table [ {xi, y1 [xi], y2 [xi], ..}, {xi, x}] Table will "do the For loop" while building matrix, in this case xi will take each value of x. And if y functions is also an array, you can use a nested Table: matrix = Table [ {xi, Sequence@@Table [y [xi,j], {j, n}]}, {xi, x}] asics gel kanaku 4 black

Symbolic Matrices in Mathematica with unknown dimensions

WebA matrix function transforms a matrix to another matrix. For convergent power series, MatrixFunction [f, m] effectively evaluates the power series for the function f with ordinary powers replaced by matrix powers. » The function f should be a unary differentiable or symbolic function. MatrixFunction works only on square matrices. WebMar 7, 2013 · I'm trying to create a matrix in which the elements are functions of two variables, but I can't figure out how to do it. Is it possible? The only way I could figure out is to define the matrix in terms of two variables, then replace those variables with values later on. Here's my code: ataman m2r airgun
