Error with array indices

This error keeps coming up. Any thoughts?

Array indices must be positive integers or logical values.

Error in Prob3_4_2 (line 17)

T(loop)= Tmean + (Tpeak - Tmean)*cos(w((D(loop))-205));

Answer 1

w*

That is, madhan is suggesting that you are missing a multiplication between w and the D(loop)-205 values.

Thank you!! I guess the longer you look at something the harder it is to see error.

That is the reason of this community’s existence ;)

By the way, MATLAB has absolutely no implied multiplication, anywhere that I have been able to find. Not even in the internal language used by the Symbolic Toolbox.
