HI.I need to find the energy corresponding to masses from 1 kg to 10^6 kg and need to use the logspace function to create an appropriate mass vector. i try make and ue the code below but i failed. can u help me tell which step is wrong?

Function used:

function output=energy(m,c)
output=(m*c^2);
end
c=2.9979*10^8;%speed of light in vacuum in metre per second
m=logspace(1,10^6);%mass in kg
E=energy(m,c^2);
