i'm trying to insert an equation and plot it, but i couldn't because i keep getting errors like : matrix dimensions must agree, or inner matrix dimensions must agree. http://www4.0zz0.com/2012/11/25/10/272913238.png this is the equation. M has a value of 1 to 5 with an increment of 0.5. Q has a value of 0 to 1 with an increment of 0.1. http://www4.0zz0.com/2012/11/25/10/700692428.png the plot is something like this. i tried to split the equation into parts, so it would be easier for me to insert it i'm having a problem with the last part, i get this error e=q./m(1-sqrt(1-(q./m).^2)); Subscript indices must either be real positive integers or logicals.
