How do I directly assign the two roots of a quadratic to an array?
显示 更早的评论
Hi,
sorry I'm new to this so I may use wrong terms and such. When using roots for a quadratic, you get 2 values...how do I have these two values assingned to 2 variables directly?
I thought it would be, for example:
[x1, x2] = roots((x^2)-4)
as in x1 = 2 and x2 = -2. But then I get the error 'too many output arguments'.
Thanks

x=roots([1 0 -4]);
x(1)
x(2)
