hi guys, I want to make a spectral RollofPoint of speech and when I enter this code from mathworks, I get this error that the variable t1 is not declared, even though I declared it. Please I will be happy for every piece of advice.

You have to run code so that the variables appear in your workspace. go to the editor tab and press "run". the editor tab appears when you click into the code section.

Do you get an error when you execute the code? I would expect that you get an error message when you run the code, because you use r1 in the line 4 before you calculate it in line 5. Switch the lines 4 and 5.
