How to solve equation with MatLab?

It is quite simple.

Way1:

using solve method.

Step1:

Declare symbolic variable.

Step2:

Declare the equation.

Step3:

using solve method. Then you will get a struct field.

I wanna solve the system of equations.

I write the following code.

%clear workspace

clear

%clear command window

clc

%way1:

%solve it

syms x y z;

equ1=3*x-3*y+z==2

equ2=x-y+z==1

equ3=7*x+5*y-z==-5

%find a solution of equation

sol=solve([equ1,equ2,equ3],[x,y,z])

%ans

x=sol.x

y=sol.y

z=sol.z

[NOTE]

syms must be seperated in space instead of ','.

such as syms x,y,z; is not acceptable.
