Replace the parameter k with a new symbolic variable a. First, create symbolic variables k and a . (The solver does not create variable k in the MATLAB ® workspace.) syms k a. Now, use the subs function to replace k by a in the solution vector solx, parameters params , and conditions conds. solx = subs (solx, k, a) params = subs (params, k, a ...

snew = subs(s) returns a copy of s, replacing symbolic scalar variables in s, with their values obtained from the calling function and the MATLAB ® Workspace, and then evaluates s. Variables with no assigned values remain as variables.

MATLAB 中的 subs 函数是一种通用的置换指令，它的功能是在符号表达式和矩阵中进行符号替换 / 置换操作。 此外它还提供了一种在符号计算和数值计算之间转换的一种途径。下面相机介绍一下如何进行置换和如何进行数值计算与符号计算的转换。

f_on_unit_circle=subs (F,r,1) which gives the output. F=sin (2*theta)/r^2. f_on_unit_circle=sin (2*theta) An alternative is to use the eval command. It is of the form ans=eval (S) where S is a symbolic expression for which at least one of its symbolic variables has just been given a value. If all variables are given numerical values, the answer ...

When you assign a value to a symbolic variable, expressions containing the variable are not automatically evaluated. Instead, evaluate expressions by using subs. Define the expression y = x^2. syms x y = x^2; Assign 2 to x. The value of y is still x^2 instead of 4. x = 2; y. y = x^2. If you change the value of x again, the value of y stays x^2.

Open Live Script. Create a plot. Add a title with the title function. Then, call the subtitle function, and specify the color using the 'Color' name-value pair argument. The color can be a color name, such as 'red', or you can specify a custom color using an RGB triplet or hexadecimal color code.

MATLAB: Subs Command. substitution. Is it possible to make an array in a function then substitute a certain element to another element.

subs, eval. Suppose you have a symbolic expression f which includes the symbol x and you wish to substitute for x another symbol c or a numerical value x0. Then you can use the general subs command g=subs (f,old,new) which in our cases would be g=subs (f,x,c) or g=subs (f,x,x0). Here old, new can be arrays.
