#### How to plot an equation in matlab

## What is the plot function in Matlab?

plot( X , Y ) creates a 2-D line plot of the data in Y versus the corresponding values in X . The plot function plots columns of Y versus columns of X . If one of X or Y is a vector and the other is a matrix, then the matrix must have dimensions such that one of its dimensions equals the vector length.

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

To graph a linear equation, we can use the slope and y-intercept.Locate the y-intercept on the graph and plot the point.From this point, use the slope to find a second point and plot it.Draw the line that connects the two points.

## How do you plot a straight line in Matlab?

Accepted Answer The easiest way to plot a horizontal line at ‘c1’ is simply: plot(xlim, c1*[1 1]); The xlim call returns the current value of the x-axis limits as a (1×2) vector. All you then need to do is to supply a (1×2) vector at the value of ‘c1’, and it will plot the line.

## What does plot line mean?

: a connected series of occurrences that form the plot or part of the plot in a story or drama.

## How do you plot a function?

Graphs of functions are graphs of equations that have been solved for y! The graph of f(x) in this example is the graph of y = x^{2} – 3. It is easy to generate points on the graph. Choose a value for the first coordinate, then evaluate f at that number to find the second coordinate.

## How do you plot a line?

The first step is to make sure that the equation of the line is in the Slope-Intercept Form, that is y = mx + b.Start by plotting the y-intercept which is (0, b).Find another point using the slope (m) with the y-intercept at the reference point.Connect the two points with a ruler.

## How do you graph on Simulink?

Output trajectories from Simulink can be plotted using one of three methods:Feed a signal into either a Scope or an XY Graph block.Write output to return variables and use MATLAB plotting commands.Write output to the workspace using To Workspace blocks and plot the results using MATLAB plotting commands.

## How do you save a plot plot in Simulink?

Set Scope Parameters for Logging to FileIn the Simulink Editor, double-click the Scope block.On the toolbar, click the Parameters button .Click the Logging tab.Do one of the following: Select the Log data to workspace check box. From the Save format list, select one of Structure with time , Structure , Array , and Dataset . Click OK.

## How do I plot a straight line in Matplotlib?

Use plt. plot() to plot a horizontal line Call plt. plot(x, y) with x as a sequence of differing x-coordinates and y as a sequence of equal y-coordinates to draw a horizontal line.
