Determinant of a big matrix
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.
