Matlab R2008a Symbolic Toolbox
Ans =0Symbolic simplification is not always so straightforward. Thereis no universal simplification function, because the meaning of asimplest representation of a symbolic expression cannot be definedclearly. Different problems require different forms of the same mathematicalexpression. Knowing what form is more effective for solving your particularproblem, you can choose the appropriate simplification function.For example, to show the order of a polynomial or symbolicallydifferentiate or integrate a polynomial, use the standard polynomialform with all the parentheses multiplied out and all the similar termssummed up. To rewrite a polynomial in the standard form, use the expand function.
Symbolic Math Toolbox enables you to expressions through simplification, expansion, factorization, and rewriting expressions in specific terms. You can evaluate symbolic expressions by making to replace parts of expressions with specified symbolic or numeric values.The toolbox enables you to analytically algebraic equations and systems of algebraic equations. You can solve well-posed systems of ordinary differential equations analytically to get exact answers that are free from numerical approximations. You can also make assumptions when solving to constrain your variables and solution. Symbolic Math Toolbox can solve.
You can perform analytical vector and matrix computations including calculating the curl, divergence, gradient, Jacobian, Laplacian, and potential.You can execute matrix operations and apply general symbolic functions to each element in a matrix. The toolbox enables you to study your system of linear equations by computing matrix properties such as the norm, condition number, determinant, and characteristic polynomial.You can transform, decompose, and take the inverse of your matrix. You can also get symbolic expressions for the and perform a symbolic singular value decomposition of a matrix. Symbolic Math Toolbox expands MATLAB graphics by providing 2D and 3D plotting functions for symbolic expressions and equations. You can analytically plot, and and work with parametric functions and piecewise continuous functions. You can also plot in Cartesian and polar coordinates.The toolbox enables you to convert symbolic expressions from their continuous domains to discrete domains for easy visualization in MATLAB. Using MATLAB graphics, you can create animations and customized visualizations.
Use Symbolic Math Toolbox to explicitly set the number of significant digits used in your computations and maintain that accuracy throughout your computations. You can and the tradeoff between accuracy and performance.You can use high precision arithmetic to avoid hidden round off errors, and use lower precision when performance is a concern.

Variable precision arithmetic can also be used to verify the results of an algorithm that uses standard double-precision or to provide an accurate numerical approximation when a closed form analytical solution is unavailable.Variable-precision arithmetic can be used routinely when computing workflows, including arithmetic, integration, differentiation, and solving. You can set the decimal digit accuracy as high as you need to maintain the accuracy for all symbolic math functions and operations. You can convert results to MATLAB standard double-precision. You can perform dimensional computations using. Symbolic Math Toolbox includes over for physical quantities such as mass, time, velocity, and power, as well as unit prefixes such as milli and kilo. Units are highlighted in an easy-to-read blue syntax in the MATLAB Live Editor helping you avoid mistakes when converting units. You can convert values between US or SI units or create your own custom unit systems.

For example, you can compute unit conversion factors between Celsius, Fahrenheit, and Kelvin and switch between relative temperature and temperature difference.You can perform dimensional analysis and derive physical equations from first principles by manipulating, simplifying, and solving equations with units. You can check that equations accurately represent the physics by checking for compatible dimensions and consistent units. You can non-dimensionalize equations to determine unitless characteristic constants that can be useful in describing the behavior of a system. For example, you can find the damping ratio ζ (zeta) of a mass spring system and use this to describe if the spring system is underdamped (ζ 1) or critically damped (ζ = 1). Use Symbolic Math Toolbox in the to interactively explore and rapidly develop mathematical models and algorithms.You can create live scripts, which display symbolic math computations in mathematical typeset alongside MATLAB code, formatted text, equations, images, and hyperlinks.
