They can be set by using the assume and assumeAlso functions: syms x y r1 r2 R1 R2 In the Symbolic Math Toolbox, such restrictions are called assumptions on variables. For example, the system does not know if these variables are positive or negative, if $r_1 0$, $r_2>0$, $R_1>r_1$, and $R_2>r_2$. This is because the variables $r_1$, $r_2$, $R_1$, and $R_2$ can be any complex number, unless we explicitly restrict their values. Nevertheless, we need to add one more step: specify relationships between symbolic parameters.

$y = \pm 2 \, \sqrt y^2\, \mathrm dy\, \mathrm dx.$$Īlthough the situation is more complicated now, we can still use the same strategy as above, using symbolic variables instead of numbers.

The following ellipses define outer and inner contours of the section: The following picture shows the cross section of an elliptical tube. Basic Example: Cross Section of an Elliptical Tube

You can find the source code for these plots at the end of the article. We start with a basic case involving only numeric parameters, and then make the computations more general by introducing symbolic parameters.Īll plots used in this article have been created in the MuPAD Notebook app. In this article, we use capabilities of the Symbolic Math Toolbox to compute area moments for cross sections of elliptical tubes. For example, area moments of inertia play a critical role in stress, dynamic, and stability analysis of structures. If you are interested in using MATLAB and the Symbolic Math Toolbox in teaching some basics in mechanical engineering, this might be of interest to you.Ĭomputing area moments of inertia is an important task in mechanics.

You can share your symbolic work with other MATLAB users as live scripts or convert them to HTML, Word, LaTex, or PDF documents. Your computations can be performed either analytically or using variable-precision arithmetic, with the results displayed in mathematical typeset. You can perform dimensional computations and convert between units. Symbolic Math Toolbox lets you analytically perform differentiation, integration, simplification, transforms, and equation solving. The toolbox provides functions in common mathematical areas such as calculus, linear algebra, algebraic and differential equations, equation simplification, and equation manipulation. In the MATLAB ® Live Editor, you can get next-step suggestions for symbolic workflows. You can create, run, and share symbolic math code. Symbolic Math Toolbox™ provides functions for solving, plotting, and manipulating symbolic math equations.
