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.

When mathematical formulas involve matrices and vectors, writing them using symbolic matrix variables is more concise and clear than writing them componentwise, sym matlab. To remove assumptions, use one of these options: sym matlab x or syms f x clears all assumptions from x.

The toolbox provides functions in common mathematical areas such as calculus, linear algebra, algebraic and differential equations, equation simplification, and equation manipulation. Symbolic Math Toolbox lets you analytically perform differentiation, integration, simplification, transforms, and equation solving. You can perform dimensional computations and convert between units.

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. You can then use the variable x in the MATLAB workspace for symbolic workflow, such as finding the roots of a polynomial. You can then use the variable f1 in the MATLAB workspace for symbolic workflow, such as finding the zeros of a sine function. When you assign a number to the MATLAB variable x , the number is represented in double-precision and this assignment overwrites the previous assignment to a symbolic variable.

The result is a cell array of symbolic matrices. This means that whatever a symbolic variable stores are not a value the computer can compute until it is assigned a numeric value. To remove assumptions, use one of these options: assume x,'clear' removes all assumptions affecting x. Use sym to refer to an existing symbolic variable. The available assumptions are 'integer' , 'rational' , 'real' , or 'positive'. Suggest changes. Symbolic Math Toolbox Perform symbolic math computations. Close Mobile Search. The class of x becomes double. Doesn't seem to me that str2sym works for what I want The sym function also lets you define a symbolic matrix or vector without having to define its elements in advance.
