## What does %% do in MATLAB?

Description: The percent sign is most commonly used to indicate nonexecutable text within the body of a program. This text is normally used to include comments in your code. Some functions also interpret the percent sign as a conversion specifier.

## How do you define a symbol in MATLAB?

The first command creates a symbolic variable x in the MATLAB workspace with the value x assigned to the variable x. The second command creates a symbolic variable y with the value y. With syms, you can create multiple variables in one command. Create the variables a, b, and c.

## How do you define a boundary in MATLAB?

k = boundary( x, y ) returns a vector of point indices representing a single conforming 2-D boundary around the points (x,y). The points (x(k),y(k)) form the boundary. Unlike the convex hull, the boundary can shrink towards the interior of the hull to envelop the points.

## How do you plot a 3 axis graph in MATLAB?

plot3( X, Y, Z ) plots coordinates in 3-D space.

1. To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length.
2. To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors.

## What does || mean in Matlab?

The “|” operator is an element-wise operator, intended to be used on arrays element-by-element. The “||” operator is a short-circuiting operator restricted to be used on scalars only. See the doc: https://www.mathworks.com/help/matlab/logical-operations.html.

## How do you express or in Matlab?

The short-circuit OR operator is ||. When you use the element-wise & and | operators in the context of an if or while loop expression (and only in that context), they use short-circuiting to evaluate expressions.

## What is Heaviside MATLAB?

H = heaviside( x ) evaluates the Heaviside step function (also known as the unit step function) at x. The Heaviside function is a discontinuous function that returns 0 for x < 0, 1/2 for x = 0, and 1 for x > 0.

## What is the meaning of MATLAB?

The name MATLAB stands for matrix laboratory. MATLAB was originally written to provide easy access to matrix software developed by the LINPACK and EISPACK projects, which together represent the state-of-the-art in software for matrix computation.

## What is a symbolic function in MATLAB?

Symbolic functions represent math functions. Use symbolic functions for differentiation, integration, solving ODEs, and other math operations. Create symbolic functions by using syms. Note. Symbolic functions must be functions of symbolic variables.

## What are boundaries?

A boundary is a real or imaginary line that separates two things. In geography, boundaries separate different regions of the Earth.

## How do you solve boundary value problems in MATLAB?

To solve this equation in MATLABĀ®, you need to write a function that represents the equation as a system of first-order equations, write a function for the boundary conditions, set some option values, and create an initial guess. Then the BVP solver uses these four inputs to solve the equation.

## How do you fill a shape in MATLAB?

The fill function creates colored polygons.

1. fill(X,Y,C) creates filled polygons from the data in X and Y with vertex color specified by C.
2. fill(X,Y,ColorSpec) fills the polygons with the color specified by ColorSpec, which can be one of the following values:
3. fill(X1,Y1,C1,X2,Y2,C2,)

## Can we have multiple 3d plots in Matlab?

Can we have multiple 3d plots in MATLAB? Explanation: The plot3() function is a pre-defined function in MATLAB. So, it will allow the use to generate multiple 3d plots. This is inherent to the system.
