Representing Unit Step Function in MATLAB

[DefaultName]

How do you represent a unit step in MATLAB as ONE function, y , for example. I know only how to graph multiple vectors on top of the same graph (using hold on/off) and getting the graph output, but i can't represent it as a function itself.

Any ideas?

If I understood your question correctly, you can do

y = (t>=0)

*Note : You have to predefine the vector t.

for the unit step function y = u(t)

Or use heaviside function.

To represent a unit step function in MATLAB as a single function, you can use the "heaviside" function. This function takes in a single argument and returns a value of 0 for any input less than 0, and a value of 1 for any input greater than or equal to 0. This is essentially the definition of a unit step function.

For example, if you want to represent the unit step function as y = u(x), you can use the following code in MATLAB:

x = -5:0.1:5; % define a range of x values
y = heaviside(x); % calculate y values using the heaviside function
plot(x,y) % plot the unit step function
xlabel('x')
ylabel('y')
title('Unit Step Function')
grid on % add grid lines to the plot for better visualization

This will give you a plot of the unit step function with a step at x=0. You can also adjust the range of x values to fit your specific needs.
