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.

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.

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.
