## How do you plot a math function in Matlab?

MATLAB – Plotting

- Define x, by specifying the range of values for the variable x, for which the function is to be plotted.
- Define the function, y = f(x)
- Call the plot command, as plot(x, y)

**How do you plot letters in Matlab?**

Direct link to this answer

- x = randi(10, 1, 5); % Create Data.
- y = randi(10, 1, 5);
- L = strsplit(sprintf(‘%c\n’,’A’:’E’)); % Letter Labels.
- figure(1)
- plot(x, y, ‘+r’)
- text(x, y, L(1:length(x)), ‘HorizontalAlignment’,’center’, ‘VerticalAlignment’,’bottom’)
- axis([-0.5 10.5 -0.5 10.5 ])

### How do you plot a symbolic expression in Matlab?

Examples

- Plot Symbolic Expression. Plot tan(x) over the default range of [-5 5] .
- Plot Symbolic Function.
- Plot Parametric Curve.
- Specify Plotting Interval.
- Plot Multiple Lines on Same Figure.
- Change Line Properties and Display Markers.
- Control Resolution of Plot.
- Modify Plot After Creation.

**What does Fplot do in Matlab?**

fplot plots a function between specified limits. The function must be of the form y = f(x), where x is a vector whose range specifies the limits, and y is a vector the same size as x and contains the function’s value at the points in x (see the first example).

#### How do you plot an equation?

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

**How do you write E in MATLAB?**

The exponential function and the number e as exp(x) so the number e in MATLAB is exp(1).

## What is the difference between plot and Ezplot in Matlab?

Direct link to this comment. ezplot returns a handle to the plot objects created; fplot returns the [X,Y] points created.

**What is f plot MATLAB?**

fplot( f ) plots the curve defined by the function y = f(x) over the default interval [-5 5] for x . example. fplot( f , xinterval ) plots over the specified interval. Specify the interval as a two-element vector of the form [xmin xmax] .

### How do you plot an equation on a graph?

Have a go

- Click to see a step-by-step slideshow.
- YOU WILL NEED: A whiteboard.
- STEP 1 – Draw a table of values for the x and y coordinates.
- STEP 2 – Using the equation y = 2x + 1, calculate the value of y by using the x value in the table.
- STEP 3 – Draw a graph and label the x axis 1 to 4 and the y axis 1 to 9.
