Why do I receive the error: Unrecognized function or variable 'V_o'?

Please guide me to solve the following error:

Warning: The specified buffer for 'Convertidor_Boost/Mean/Model/Transport Delay' was too small. During simulation, the buffer size was

temporarily increased to 106496. In order to generate code, you need to update the buffer size parameter

Unrecognized function or variable 'V_o'.

Error in Run_Convertidor_Boost (line 62)

plot(tt1,V_o)

Thank you so much,

The most likely reason is that you have not yet defined a variable with that name in your code. Did you define a variable V_0 or V_O instead of V_o?

% Recreated the error message
% Define a variable tt1 but not V_o
tt1 = 1:10;
plot(tt1,V_o)

Unrecognized function or variable 'V_o'.

This is a mistake I make myself at times. o and 0 live right next to each other on the keyboard. And they can look a lot alike, depending on the font. So I'd bet @Cris LaPierre is right.
