Matlab symbolic toolbox

You can create, run, and share symbolic math code.

Help Center Help Center. You can create, run, and share symbolic math code. 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. Your computations can be performed either analytically or using variable-precision arithmetic, with the results displayed in mathematical typeset.

A variable x must have a numerical value or array values before expressions involving x can then be evaluated. For example if you merely enter the single command sin x after the prompt you receive the error message. Each expression can be given a variable name also symbolic thereby allowing algebraic, trigonometric and other functional manipulations and simplifications as well as permitting differential and integral calculus. You will be solving and computing with mathematical symbols rather than numbers. Enter the following and examine the output:. You notice that no attempt has yet been made to simplify z. The default format is an integer or rational fraction. If this is not possible, a real number will be approximated by a fraction of large integers. In each of the following cases the symbolic expression in the middle column results from the corresponding sym command, while the last column results if you then apply the double Alternative formats can be viewed by entering help sym.

The following example illustrates how to take a first derivative of a symbolic expression:. For multivariable expressions, you can specify the differentiation variable.

Help Center Help Center. Functions are called using the familiar MATLAB syntax and are available for integration, differentiation, simplification, equation solving, and other mathematical tasks. You can convert symbolic results to numeric results and use them outside Symbolic Math Toolbox. Explores the physics of the damped harmonic oscillator by solving the equations of motion in the case of no driving forces. This example investigates the cases of under-, over-, and critical-damping. Solve the equation of motion of a simple pendulum analytically for small angles and numerically for any angle. Finds the average radiation power of two attracting charges moving in an elliptical orbit an electric dipole. Model a bouncing ball, which is a classical hybrid dynamic system. This model includes both continuous dynamics and discrete transitions.
