How can we possibly help you considering what you've given us? It's probably a syntax error where you're missing an end or brace or something. Why don't you post the error message so you can get some help? And since this kind of error often involves nearby lines, post the chunk of code around the line that it complains about.

Open the file in the editor and look for red MLint marks on the right side.

Pr_two_ray = Pt * (Gt * Gr * (transmitterHeight * receiverHeight)^2) ./ (distance.^4 * L);

Unrecognized function or variable 'Pt'.

I do not see any problems with that code.

Pt = rand();
Gt = rand();
Gr = rand();
transmitterHeight = rand();
receiverHeight = rand();
distance = rand();
L = rand();

Pr_two_ray = Pt * (Gt * Gr * (transmitterHeight * receiverHeight)^2) ./ (distance.^4 * L)

Pr_two_ray = 23.1791

Make sure Pt is defined before you try to use it.

Gt = rand();
Gr = rand();
transmitterHeight = rand();
receiverHeight = rand();
distance = rand();
L = rand();

Pr_two_ray = Pt * (Gt * Gr * (transmitterHeight * receiverHeight)^2) ./ (distance.^4 * L);

Unrecognized function or variable 'Pt'.
