I am getting the error "Array indices must be positive integers or logical values" on solving a cubic equation.
c1 = 0.6;
c2 = 0.095;
c3 = 47500;
c4 = 0.0026;
wBar = [-c2*c4 -0.106*c2 -36.6*c2 c3*c1];
disp(roots(wBar));
Kindly help.

Works for me. I suspect that earlier you accidentally defined a variable named roots and it is still in you workspace.
clear roots

Either you must have a variable named roots or disp , therefore clear it from workspace:
clear roots disp
