Help Center Help Center. These two functions are conceptually different. The sym function refers to a symbolic object that can be assigned to a MATLAB variable with the same name or a different name. The following examples discuss the differences between the syms and sym functions. For more examples on the use cases of each function, see syms or sym. The syms function creates a variable dynamically. For example, the command syms x creates the symbolic variable x and automatically assigns it to a MATLAB variable with the same name.

Help Center Help Center. This example shows how to create symbolic numbers, variables, and expressions. To learn how to work with symbolic math, see Perform Symbolic Computations. You can create symbolic numbers by using sym. Symbolic numbers are exact representations, unlike floating-point numbers. Create symbolic numbers by using sym and compare them to the same floating-point numbers. The symbolic numbers are represented in exact rational form, while the floating-point numbers are decimal approximations. Calculations on symbolic numbers are exact. Demonstrate this exactness by finding sin pi symbolically and numerically. The symbolic result is exact, while the numeric result is an approximation.

Use the sym function to refer to an exact symbolic number without floating-point approximation. What kind of Experience do you want to share?

Chaotic Swinging Sticks. Dependency-based Test Selection. Start Hunting! I am pleased to introduce guest blogger Kai Gehrs. Kai is a developer for the Symbolic Math Toolbox. This article discusses how symbolic workflows can be improved by using symbolic equations and symbolic functions in MATLAB. Symbolic equations and symbolic functions were introduced in the Symbolic Math Toolbox in Release a.

You can perform dimensional computations and convert between units. For example, syms x 3 matrix creates a square 3 -by- 3 symbolic matrix variable. Tips You can create multiple symbolic objects in one call. Search MathWorks. Suggest Changes. This example shows how to create symbolic numbers, variables, and expressions. Set Assumptions While Creating Variables. If you declare a variable using syms , existing assumptions are cleared. You have a modified version of this example. Do you want to open this example with your edits? Instead, to create symbolic expressions first create symbolic variables using 'syms'.

Matlab has a powerful symbolic math ability. Rather than making calculations on known numbers, we can make calculations on symbolic expressions. Matlab can tell us.

Do you want to open this example with your edits? No, overwrite the modified version Yes. The toolbox provides functions in common mathematical areas such as calculus, linear algebra, algebraic and differential equations, equation simplification, and equation manipulation. Show that the converted result in Y is equal to the sum of two matrices of symbolic scalar variables. Use these syntaxes to create symbolic matrix functions of type symfunmatrix :. That is, each variable name must begin with a letter and can contain only alphanumeric characters and underscores. Related Articles. You may receive emails, depending on your communication preferences. To create such a matrix, the syms keyword takes the following form:. Vector, matrix, or array dimensions, specified as a vector of integers. Select the China site in Chinese or English for best site performance.
