how to plot in simulink

i designed a simulink model where i was in need to plot the result vectro obtained , so how can i do that as i didnt get any method to do that

i want to plot my ouput vs input which are both vectors

You can plot the output versus input vectors in Simulink using the To Workspace block for saving the vectors and then using MATLAB’s plot function.

You can Save the vectors in Simulink, run the model and plot the vectors in MATLAB

plot(input, output)
xlabel('Input')
ylabel('Output')
title('Output vs Input')

Hello Prajwal N,

What Manikanta Aditya suggests works but if you do not want to save your output and just want to plot,

you can use the "scope" block for plotting the “input” and “output” of your Simulink model.

Here is the documentation for the same:

This would resolve your issue.

Yes, even this is an alternative that works. Thanks @Pramil

[Prajwal N]

@Pramil, but the scope gives only plots of time domain right means x axis has time..or can we change x axis to our input vector. Or using To workspace is the only method

[Pramil]

Prajwal N the "Scope" will plot your data against time, in cases where you want to plot your "Input" on x-axis and "Output" on y-axis, use the "XY-Graph" block.

You can refer this link for more information about the block:
