Nov 14, 2018 · **ROOTS**=solve (Z^3 == -8-3i,Z) logical (sum (**ROOTS**)==0) More Answers (1) James Tursa on 14 Nov 2018 1 Link Another way is to simply use the **roots** ( ) function with appropriate polynomial coefficients: >> **roots** ( [1 0 0 (8+3i)]) ans = 0.8036 + 1.8798i 1.2261 - 1.6359i -2.0297 - 0.2439i. Web. Two simple options:** x^ ( 1 /** 3) Or,** nthroot (x,** 3) Be very careful though. If x is negative, it will return a complex number, because there are indeed THREE cube roots of a negative number. Two of them are complex. nthroot will give you the root you would expect however. ( -2 )^ ( 1 / 3 )ans = 0.62996 + 1.0911i nthroot ( -2, 3 )ans = -1.2599.. Jan 10, 2019 · I would like to plot the **roots** of the cubic equation x^ {3}+Ax^ {2}+1=0 **in matlab**. I know that there are 3 real **roots** for A<-1.88 and 1 if A>-1.88.. Jan 10, 2019 · I know that there are 3 real **roots** for A<-1.88 and 1 if A>-1.88. I would like to plot the 3 real **roots** as a function of A and when it switches to 1 real **root** and 2 complex to plot the real **root** and the real part of the complex conjugate solutions all in the same plot (perhaps as 2-3 graphs).

I have to modify the above program to use the **cube** **root** algorithm to approximate the **cube** **roots** to 10 decimal places of the following start with p0=2 and approximate 7^ (1/3) Here is the **cube** **root** algorithm pk = ( 2p (k-1) + A / p^2 (k-1) ) / 3 for k = 1,2,3 ... Note... k and k-1 are in subscripts of p and p square. Use your routine to find the **cube** **roots** of a = 3+ 4i, 10 - 5i, -1 + 2i. For the current homework, you want to find the **root** of a complex-valued function f of a complex number z=2_1+iz_2: (Z) = 2^3 - a where a is also complex, a=a_1+ia 2. Here, z_1,z_2,a_1, a 2 are all real and i = sqrt {-1}.. Nov 24, 2021 · Two simple options: Theme Copy x^ (1/3) Or, Theme Copy nthroot (x,3) Be very careful though. If x is negative, it will return a complex number, because there are indeed THREE **cube** **roots** of a negative number. Two of them are complex. nthroot will give you the **root** you would expect however. Theme Copy (-2)^ (1/3) ans = 0.62996 + 1.0911i. Write a **MATLAB** script for computing the **cube** **root** of a number, x = , with only basic arithmetic operations using Newton’s method, by finding a **root** of the function f (x) = x 3 − a. Run your program for a = 0,2,10. For each of these cases, start with an initial guess reasonably close to the solution.. Web. Web.
