Question

The command to find the eigen vector of a matrix in matrix form is _____________

(a) eig(a,matrix)

(b) eig(a,’matrix’)

(c) eigen(a,matr)

(d) eig(a)

The question was posed to me in an interview.

My question is from Linear Systems in chapter Beyond the Basics of MATLAB

Answer 1

Right answer is (b) eig(a,’matrix’)

Easy explanation: The in-built function to find the eigen values of any matrix in MATLAB is eig(a). But, to display the result in matrix form- we use eig(a,’matrix’). This nature of the eig command is in-built in MATLAB.
