What does matlab syms mean?

syms in matlab means defining multiple variables.

1. Create symbolic variables x and y

For example: syms x y

2. List all symbolic variables, functions and arrays

Create some symbols Variables, functions and arrays such as: syms a f(x); A = sym('A',[2 3]);

Use syms to display a list of all symbol objects currently existing in the MATLAB workspace. Then the symbol variable is: A A f x;

does not display a list, but returns a cell array of all symbol objects by providing output to syms. For example: S = syms; S = 4×1 cell array {'A'} {'a'} {'f'} {'x'};

Extension Information:

matlab syms x y 用法
>> help syms
syms - Shortcut for creating symbolic variables and functions. 快捷方式创建符号变量var1
This MATLAB function creates symbolic variables var1 ...
syms var1 ... varN
syms var1 ... varN set  集合
syms var1 ... varN clear
syms f(arg1,...,argN)

Define a, b, c, d as symbolic variables.

For example:

Enter the expression s=ax^4 bcosy-xy.

>>a=4;b=6;
>>syms x y
>>s=a*x^4+b*cos(y)-x*y

Only in this way can the value be obtained. Otherwise, an error is reported.

>> syms x y
>> x
<span></span>x =<span></span>x
>> y
<span></span>y =<span></span>y
>> a=4;b=6;
syms x y
s=a*x^4+b*cos(y)-x*y
s =<span></span>4*x^4 - y*x + 6*cos(y)
