MATLAB: Matrix index is out of range for deletion

Question

Hello, I am trying to delete certain rows of an 1D array if a conditional statement is true.

My code is:

for i = 1:length(TF)
    if TF(i) == 1
        pitch(i) = []; 
    end
end 

for the length of TF (a logical array) i evaluate TF as true or false and if it is true i want to delete the value in the array called pitch at that corrasponding index.

I am getting an error message that says "Matrix index is out of range for deletion."

I cannot seem to fix this probem and would appreciuate any help or suggestions.

Thank you,

Adam

 pitch(TF == 1) = []
