There's no goto in matlab, and there is no need to. You could just as well code your algorithm as:
%... step 1 to 29
condition = false;
while ~condition
%... step 30 to 60
condition = sometest
end
%... step 61 to 80

Another option is to build your code as a state machine. A simple way to implement a state machine is just with a while loop and a switch. With 80 states, it's going to be a bit unwieldy to code:
step = 1;
while true
switch step
case 1
%do step 1
step = 2;
%... case 2 to 59
case 60
%do step 60
if somecondition
step = 61;
else
step = 30;
end
%... case 61 to 79
case 80
%do step 80
break;
end
end

Goto is not available in basic MATLAB but is available in a File Exchange Contribution for the amusement of those who know not to use GOTO, and for the frustration of those who insist they need GOTO.

'amusement' is a key word here. That FEX contribution should not be used for anything else. I don't think the warning is strong enough on the FEX page and we may end up having some people trying to use it without understanding the implication.
That goto is basically an interpreter built on top of matlab own interpreter. As soon as you hit a goto, you're simply eval'ing the rest of the program line by line!
