How do you plot a math function in Matlab?

MATLAB – Plotting

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

How do you plot letters in Matlab?

Direct link to this answer

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

How do you plot a symbolic expression in Matlab?


  1. Plot Symbolic Expression. Plot tan(x) over the default range of [-5 5] .
  2. Plot Symbolic Function.
  3. Plot Parametric Curve.
  4. Specify Plotting Interval.
  5. Plot Multiple Lines on Same Figure.
  6. Change Line Properties and Display Markers.
  7. Control Resolution of Plot.
  8. 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

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