14.1.2. Task 0
Learning Objectives
Create simple UDF’s in MATLAB . Practice writing a UDF in the same file as the main script and calling the respective function in the main script. Create a simple plot in MATLAB .
Task Instructions
In this task, you will be writing a simple UDF in MATLAB and learning how to create a simple plot.
Make a copy of the ENGR133_MATLAB_Template.m MATLAB template and rename the file to ma3_pre_1_username.m .
Make sure to fill out all header information, including a short description of the code.
In the Initialization Section, initialize the variable, x
Hint
Use the linspace () MATLAB to do this.
Next, initialize the variable, y, to be \(x^2\) .
In the Outputs Section, create a user-defined function that takes in two variables, x and y, and returns nothing.
In the user-defined function plot the two variables x and y. When plotting the variables, make the line blue with
dashes and circles as the markers.
Title the plot, “My Practice Plot”, and make sure to label the x-axis and y-axis. Also turn the grid on for the
plot.
In the Calculations Section, call the user-defined function with the x and y variables.
Below is what your plot should look like.
