## How do you type Theta symbol in MATLAB?

Direct link to this answer

- theta = pi/4;
- result = 2*sin(theta); % <– if theta is in radians.
- theta = 45;
- result = 2*sind(theta); % <– if theta is in degrees.

**How do you type infinity symbol in MATLAB?**

MATLAB® represents infinity by the special value Inf . Infinity results from operations like division by zero and overflow, which lead to results too large to represent as conventional floating-point values.

**How do you enter equations in MATLAB?**

To insert an equation interactively:

- Go to the Insert tab and click Equation. A blank equation appears.
- Build your equation by selecting symbols, structures, and matrices from the options displayed in the Equation tab.
- Format your equation using the options available in the Text section.

### How do you get a symbolic Math Toolbox in MATLAB?

If you have the Symbolic toolbox, then you can download the MATLAB install it with the symbolic toolbox. If you already have MATLAB installed, then you can click you can click Add-ons and search for the symbolic toolbox and install it.

**What is symbolic math MATLAB?**

Symbolic Math Toolbox™ enables you to perform symbolic computations from the MATLAB® command line by defining a special data type — symbolic objects. Functions are called using the familiar MATLAB syntax and are available for integration, differentiation, simplification, equation solving, and other mathematical tasks.

**How do you write a subscript in MATLAB?**

To add subscripts to symbolic variables in live scripts, append the corresponding index to the variable using one underscore ( _ ). For example, create two symbolic variables with subscripts using syms . Use these variables in an expression.

#### Can I use latex symbols in MATLAB?

By default, MATLAB supports a subset of TeX markup. For a list of supported symbols, see the documentation . For more symbols, you can use LaTeX markup by setting the Interpreter property to ‘latex’. Use dollar symbols around the text.

**What are the mathematical symbols in Tex?**

All the predefined mathematical symbols from the TeX package are listed below. More symbols are available from extra packages. ! {\\displaystyle !\\,} ! ∃ ! {\\displaystyle \\exists !} \\exists! The prefix arc used for inverse circular trigonometric functions is the abbreviation for arcus.

**How do I convert Tex characters to MATLAB text?**

Create text that contains TeX characters and add the text to the line plot. If you include the ‘literal’ argument, texlabel interprets Greek variable names literally. Add text with the literal variable names to the line plot. Input MATLAB expression, specified as a character vector or string scalar.

## What does texlabel do in MATLAB?

txt = texlabel(f) converts the MATLAB ® expression f into the TeX equivalent for use in text. texlabel converts Greek variable names (for example, lambda, delta, and so on) into a character vector that is displayed as Greek letters.
