Unable to use a value of type tf as an index. How to fix?

28 visualizaciones (últimos 30 días)
num=[(-number1),(number2)];
den=[(number3), (number4))];
sys1 = tf(num, den);
fb = bandwidth(sys1)
Having issues when running this saying that I am unavailable to use value of TF as an index. Any suggestions to fix this?

You will find that bandwidth is a variable but that you are trying to use it as a function call.

Hi Walter, how else would I use bandwidth then?

Rename the variable you've created that's named bandwidth to something else. While that variable exists in the workspace you will be unable to call the bandwidth function.

The error message "Unable to use a value of type tf as an index" suggests that there is a syntax error in the code. It seems like there is an extra parenthesis in the den array definition which is causing the problem.
You can try this code:
number1 = ...; % Your value for number1
number2 = ...; % Your value for number2
number3 = ...; % Your value for number3
number4 = ...; % Your value for number4
num = [-number1, number2];
den = [number3, number4];
sys1 = tf(num, den);
fb = bandwidth(sys1);
Thanks,
Ayush
