Determinant of matrix mathematica
WebOct 27, 2015 · I am trying to solve a linear equation in x, where the equation is given by Det [M]==0. The M is a symmetric matrix (dimensions 47x47) with an element equal to x and all other elements are equal to numbers ranging from 1 to 10^4. So, Det [M] is a linear equation in x. I could get a solution for a 11x11 matrix using 'Solve', but when the ... WebNov 9, 2024 · which shows that the determinant is zero. This is a medium sized matrix at most - to find the determinant for a actual large matrix ( n > 100 ), look up RRQR. In this particular case, the fifth column is equal to the sum of the second and fourth columns; so the determinant is zero.
