MATLAB: Shortening nested If statements

compactifshorten

HI Friends,
I am trying to shorten this nested if statement, is there a way to make it more compact ?
GR = [3.78 2.06 1.58 1.21 0.82]
for i=1:x
ig(i) = 3.78;
N(i) = Vel_mps(i)*io*ig(i)*60/pi/Dt;
% Gear change with speed exceeding 2000 rpm
if N(i) > Nopt
ig(i) = 2.06;
N(i) = Vel_mps(i)*io*ig(i)*60/pi/Dt;
if N(i) > Nopt
ig(i) = 1.58;
N(i) = Vel_mps(i)*io*ig(i)*60/pi/Dt;
if N(i) > Nopt
ig(i) = 1.21;
N(i) = Vel_mps(i)*io*ig(i)*60/pi/Dt;
if N(i) > Nopt
ig(i) = 0.82;
N(i) = Vel_mps(i)*io*ig(i)*60/pi/Dt;
end
end
end
end
end

Approximately:
GR = [3.78 2.06 1.58 1.21 0.82];
magic_constants = [3.78 2.06 1.58 1.21 0.82];
for i=1:x
j = 0;
Less = false;
while ~Less & (j<numel(magic_constants)
j = j + 1;
ig(i) = magic_constants(j);
N(i) = Vel_mps(i)*io*ig(i)*60/pi/Dt;
Less = N(i) <= Nopt;
end;
end;
